Best Paperless Device: Hybrid / Convertible

The main 1:1 paperless device considerations I addressed in the previous post were:

  1. eBook accessibility
  2. Affordability
  3. All-day battery life
  4. Document creation
  5. Multimedia (photo/audio/video) production
  6. Access all websites
  7. Handwriting / drawing capability (notes, artwork)
  8. Compatibility with peripheral devices

The needs of my classroom — a self-contained, multiple-subject, 6th grade classroom — are varied and run the gamut from reading, writing, and research to science labs, art projects, and video production.  I need a device that can be used for typed documents and standard “computer” purposes, can access every online educational resource available to us (including Flash or Java ones), but in going paperless I also need one that allows for writing, drawing, art, and multimedia production. In other words, I need a device that can do it all. I want my students to be able to have their cake and eat it, too.

This is where hybrid or convertible devices shine. With touch screens, accelerometers, built-in cameras — and sometimes active digitizer pens, as well — these devices allow you to get any of the benefits of a tablet, but they also feature full-fledged operating systems that allow for the unrestricted website access, productivity software, and keyboarding capabilities of a laptop or desktop computer.

But even in the subcategory of hybrids/convertibles, there are a lot of different options: some are touch-screen ultrabooks with larger screens and full-powered processors; others are netbooks (“netvertibles”), with smaller screens and less powerful processors, but much better battery life; while others primarily take a tablet format, with long battery life and built-in cameras, but keyboards must be added or attached separately.  There are even different operating systems available on these devices, but the vast majority are running Windows 8.

After researching and trying out several devices, the one I chose to best fit the needs of my classroom was the Lenovo ThinkPad Tablet 2:


  • Very slim, lightweight, and portable
  • Rugged, rubberized casing with strong screen (Dragontrail glass)
  • Durable, capable, natural-feeling keyboard (sold separately)
  • Decent front and rear cameras (2 megapixel and 8 megapixel)
  • Capacitive touch + active digitizer for accurate writing/drawing
  • USB, HDMI, SD storage, and SIM card slot
  • Supports the greatest range of peripheral devices (anything that works on Windows via bluetooth or USB)
  • Access 100% of websites, including Flash, Java, Silverlight, etc.
  • 10 hours of battery life (even with non-stop use)


  • Separate keyboard must be used
  • Lenovo’s keyboard is expensive ($100+) — but you can use any bluetooth or USB keyboard
  • Weaker processor and graphics than laptops/ultrabooks

My first inclination was actually not to use a tablet-format device. Because online research and typed document creation are such essential parts of the 6th grade curriculum, I felt it would be preferable to have a device with keyboard attached (while still including touch-screen tablet and writing/drawing capabilities.) There are actually very few options in this configuration; most of the devices that have active digitizer pens are in tablet format.

However, there was one very intriguing option: the CTL 2go PC NL4, which is a device built to spec as an Intel Classmate PC:

This is a “netvertible” (convertible netbook that can also be used as a tablet) that was designed from the start to be used by children and schools. As such, it has lots of classroom-friendly features, including ruggedized casing, spill-resistant keyboard, and installed software apps for IT management, teacher administration, and classroom activities including camera applications and art/drawing software. There’s a lot to like here, and I love the idea of the Intel Classmate PC: a device that “does it all” and specifically addresses the needs of students and teachers in a classroom. Unfortunately, the execution and hardware decisions involved in architecting this device prevent it from being a viable choice for my classroom, due to sub-par built-in camera (less than 1 megapixel resolution) and, especially, insufficient battery life (4.5 hours).

Various other options were contenders, as well — all of which are versatile devices, but each of which has some important drawbacks to consider…

Other Contenders

1) CTL 2Go NL4 – Intel Classmate PC (Win 8)

As mentioned above, the first — and most tempting — device for a 1:1 paperless classroom was the CTL 2go Convertible netbook/tablet PC. Previous generations of this device used a resistive touch screen instead of a capacitive one — this worked well for writing, but not for finger-touch interactions or multi-touch gestures.  Additionally, older versions of Windows (before Windows 8) were rather clunky and not ideal for touch-screen formats. Finally, the older 2go PCs had weak Atom processors which were barely sufficient, and struggled to handle some tasks (including art and drawing apps that used the pen!)

The newest iteration, the NL4, has fixed many of these issues, due to now using a capacitive touch screen (good for fingers) combined with active digitizer (good for writing and drawing), as well as a more powerful processor. Unfortunately, the Celeron processor it now uses has meant a sacrifice of several hours of battery life, for not much of a boost in performance (3.4 Windows Experience score — compare this to 3.2 for the Lenovo ThinkPad Tablet 2 which gets 100% longer battery life on a single charge.)


  • Rugged, child-proofed design: built-in handle, durable casing, spill-resistant keyboard.
  • Slightly more powerful processor (Celeron)
  • Camera swivels to be used front- or rear-facing
  • Includes Intel Learning Series Software Suite of educational and management applications
  • Capacitive touch screen plus active digitizer stylus
  • Built-in keyboard
  • Access 100% of websites, including Flash, Java, Silverlight, etc.
  • Lots of input and output ports: audio, USB, ethernet, HDMI, VGA, SD Card


  • Only 4.5 hours of battery life
  • Celeron processor is still not very powerful
  • Low-quality camera

2) SAMSUNG ATIV SMART PC 500T (Windows 8)

The Samsung ATIV Smart PC 500T is a very similar device to the Lenovo ThinkPad Tablet 2, with many of the same benefits and drawbacks. The pricetag of the Samsung was more attractive — especially when considering the cost of keyboard. However, the build quality of the ThinkPad has received much higher marks and better reviews than the 500T, which has had some reports of various issues and questionable durability.


  • Very slim, lightweight, and portable
  • Less expensive than competitors, and comes with keyboard
  • Decent front and rear cameras (2 megapixel and 8 megapixel)
  • Capacitive touch + active digitizer for accurate writing/drawing
  • Access 100% of websites, including Flash, Java, Silverlight, etc.
  • USB, HDMI, SD card
  • All day battery life


  • Questionable build quality
  • Weaker processor than laptops/ultrabooks
  • Not attached to keyboard

3) Microsoft Surface Pro (Windows 8)

It would have been nice to have a more powerful processor for full-fledged computing capabilities without lag or limitations. One device that would make that possible (while still offering tablet capabilities, keyboard, and active digitizer) is the Microsoft Surface Pro.

The Surface Pro essentially has the exact same hardware as a full-fledged laptop or ultrabook — it features a Core i5 processor, the same chip found in a Macbook or Mac Mini. But it also works as a touch-screen tablet, and has an active digitizer for accurate writing and drawing with pen.

The more powerful processor has also translated into a higher pricetag (though still more affordable than a Macbook, and on par with top-end iPad), and more importantly, low battery life. However, looking into the future, the next generations of Surface (or similar device) may be the ideal classroom solution, because the newest processors (such as Intel Haswell line) will be full-powered chips with much better energy efficiency, resulting in all-day battery life.


  • Powerful Core i5 processor
  • USB, HDMI, SD card, etc.
  • Can serve as laptop, tablet, or drawing/writing tablet
  • Access 100% of websites, including Flash, Java, Silverlight, etc.
  • Run all of the full-fledged productivity Windows software
  • Active digitizer with over 1,000 levels of pressure sensitivity


  • Pricetag
  • Surface “keyboard” is not as good as larger physical/mechanical keyboard (however, any bluetooth or USB keyboard can be used)
  • Insufficient battery life (about 4 hours)

4) Samsung Galaxy Note 10.1 (android)

The Galaxy Note 10.1 is an Android tablet like many others, but a big difference is that it includes the S-pen active digitizer which opens up opportunities for precise, accurate, and natural writing and drawing, similar to this above devices. In this way, it is similar to the ATIV Smart PC 500T, but running Android instead of Windows.


  • Less expensive than some of the other options listed here
  • USB, HDMI, SD card, etc.
  • Capacitive touch screen plus active digitizer (S-pen) for more accurate writing/drawing
  • Can be used with either bluetooth or plugin keyboards
  • Android OS can be more secure than Windows in many ways
  • OS may be easier to use for students
  • Many more touch-apps than Windows 8 / Metro
  • Long battery life


  • Flash is no longer “supported” on Android, making it harder to install and use (but it can still be done)
  • No Java, Shockwave, or Silverlight websites can be used
  • Processor is not as powerful as Surface Pro or ultrabooks
  • Unable to run Windows apps, or to access any peripheral devices that require Mac or Windows drivers

5) Apple iPad (iOS)

The iPad was one of the first — and also one of the most popular — tablet devices being used in schools. For this reason, and because there are many apps available, it can be a tempting choice for a 1:1 classroom. You could certainly try a paperless classroom with iPads — it will likely work better as a paperless solution than a standard netbook, ultrabook, or Chromebook would, due to lack of any writing/drawing capabilities at all on those devices. However, there are several limitations that make it less than ideal and cause some tasks to be difficult… and others impossible.


  • More educational touch-screen apps than Android or Windows
  • Pretty secure and intuitive OS / interface
  • Has a lot of support resources (like teacher blogs, websites, recommendations, and lesson plans) available on the web
  • Newer models have better processor than Atom (which is on par with A5 chip in iPad 2)
  • Long (all-day) battery life
  • Decent-resolution front and rear cameras


  • Pricetag (although smaller and older models — iPad 2 and Mini — are more reasonably priced)
  • Not as powerful as ultrabooks or Surface
  • Lack of USB port; much more limited choice of peripherals
  • Google Docs/Drive works better on other devices
  • No active digitizer means writing and drawing cannot be done in a precise or natural way — even the best stylus pens lack pressure sensitivity and do not have a fine-tip (some mimic a fine-point by surrounding it with a clear pad that must push/slide around, making for an unnatural experience)
  • Cannot access 20% of websites (even higher percentage for interactive educational sites); Does not support Flash, Java, Shockwave, Silverlight, etc., so cannot access various educational websites, resources, and games (BBC, Scholastic, NatGeo, PBS Kids, Colonial Williamsburg, SumDog, etc.)

Convertible Tablet for Schools: Lenovo ThinkPad Tablet 2


In this video I’m going to show an example of a “convertible tablet” which just might be a great choice for schools and education: The Lenovo ThinkPad Tablet 2. Being a convertible tablet, the ThinkPad Tablet 2 is designed as a full-fledged computer inside of a touch-screen tablet format, but with an additional bluetooth keyboard base you can purchase to use it more like a laptop.

This convertible tablet format is popular right now, with other brands including the Dell Latitude 10, ASUS VivoTab, and Samsung Smart PC 500T.

I haven’t tried these other devices, but the ThinkPad Tablet 2 stood out as potentially the best of the bunch for educational use due to the fact that ThinkPads are known for rugged and durable build quality, and it comes with a Wacom digitizer stylus. The Samsung is competitively priced, but I’ve seen reviews noting somewhat questionable durability and sturdiness in its build quality. Meanwhile, the Dell Latitude 10 and ASUS VivoTab seem have some good features, but they only include the active digitizer and stylus if you opt for their highest-level models, which cost significantly more than the ThinkPad 2.

So, if you’re considering this “convertible tablet” format for a school or classroom, the ThinkPad Tablet 2 seemed like it could be the smart choice.

Yang – What’s great about the ThinkPad Tablet 2

  • Access 100% of websites and Windows programs. Like all devices running Windows 8, you can use this as a full-fledged computer. Any of the millions of programs that run on Windows can run on this, which can be important for schools that are already using certain software they would like to keep using. It’s also important for having access to various peripherals that require a real computer to install and use, like various digital microscopes or even the Kinect system.  You can also access 100% of websites on the internet, including those that require Flash, Java, Shockwave, Unity, Silverlight, or other plugins to run.  Many of these websites can’t be accessed if you use iPads, Android tablets, or Chromebooks.

  • Portable, lightweight, durable. Lenovo’s ThinkPad products are often supplied to our government and as such most of them meet rugged durability standards set by the US military. In testing the ThinkPad Tablet 2, it is very minimalist — it is very lightweight — but the plastic casing seems to be high quality and sturdy. The glass screen is a strengthened glass called Dragontrail glass that is made by Japan’s biggest glassmaker, Ashai. This glass is scratch and shatter-resistant and is about 6 times stronger than conventional glass.

    I can attest to the durability of this device — I didn’t attempt to stress-test or damage the evaluation unit, but at one point it did accidentally slide off my desk and dropped about 30” down to the hard floor, landing right on a corner. No damage occurred, not so much as a scratch on either the plastic casing or the glass screen. I do trust the durability of Lenovo ThinkPads over some other brands.

  • Wacom active digitizer. The ThinkPad Tablet 2 comes with a feature that I believe is essential for schools and education: an active digitizer. What this means is that, in addition to the multi-touch capacitive screen for finger gestures, there is also a special component to make use of a precision stylus that has a fine point just like a real pen or pencil. This is not like the stylus you might use on a regular capacitive tablet like the iPad — those stylus pens have soft, stubby tips that aren’t much better than a finger for writing or art applications. Active digitizer pens have a fine point and are pressure-sensitive which really helps for precise writing and drawing applications. The stylus for the ThinkPad Tablet 2 is fairly small and lightweight — I would personally prefer a more hefty stylus, but it does work well. It has 1,024 levels of pressure sensitivity, you can even use it as a mouse hover over objects without touching the screen, and one great feature is that there is a small storage slot that the stylus slides into at the top corner of the tablet.

  • Cameras. Like most tablets, this device has both a front-facing and rear-facing camera.  And like most tablets, the cameras aren’t amazing, but they have decent resolution and will get the job done. If you want to shoot professional level photography or video, you’ll want an actual camera — probably a digital SLR. But the cameras on the ThinkPad do a decent job, both the 2 megapixel front-facing camera for video conferencing, and the rear-facing 8 megapixel one for video and photography.

  • Battery. The ThinkPad Tablet 2 has a built-in battery which means unfortunately you won’t be able to easily remove it or swap it out with another one.  However, with 10 hours of battery life, I doubt you will ever need to. I ran a non-stop, full-screen video stream from Netflix on this device and after 6 hours I still had 40% of the battery life remaining.  That’s impressive!

And now for the Yin – A few challenges with this device:

  • Processor. The Atom Z2760 processor on the ThinkPad tablet 2 is sufficient for most educational tasks, but is still weaker than a full-fledged desktop, laptop, or ultrabook. The Atom processor is actually more powerful than the processors found in iPads and Android tablets, but it doesn’t have great graphics performance. As you can see, we get a Windows experience of 3.2 on this machine, which all things considered isn’t too bad. It will allow you to access websites, Google Docs, Microsoft Office, watch HD videos on YouTube and Khan Academy. It can even handle more complex tasks like photo and video editing, Google Earth, and even basic CAD design like SketchUp. However, it isn’t going to be sufficient if you want to do specialized tasks like cutting-edge video games, 3D graphics, or HD video editing.

  • Keyboard. Although the keyboard has a great feel and seems to be durable, it has a few negative aspects. The way the tablet sits on the keyboard is less than ideal. It simply slides into a little slot with no sort of hook or attachment mechanism. It fits snugly and feels pretty secure, but it could easily fall out if it gets bumped, especially from behind.  The stand also keeps the tablet upright at one specific angle — there is nothing you can adjust about that. The keyboard isn’t bad — the keys themselves feel and work great — but it does seem overpriced at over $100.  There also is no finger-touch pad which people are used to using on laptops; instead, there is the little red trackpoint that thinkpads are known for. This can be a little bit annoying and difficult to use. Since you have a touch-screen, you might not really need these pointer tools, but if you’re using any traditional programs that use a mouse, you’ll probably want to go ahead and use a real mouse.

  • Management. Having separate components to keep track of can make this more difficult to carry and to manage than an ultrabook or convertible ultrabook. I would suggest using only the tablet part alone for mobility and portability, while keeping the keyboard handy in a specific location to be used when you want to type and create documents. For example, at school you could store the tablets overnight in a charging cart, while students keep the keyboard easily accessible inside of their desks. If you do want to move both the tablet and keyboard around together, for about $40 you can get a sleeve designed to carry them both together.

  • Pricetag. The price of a convertible tablet is going to be more than the cost of most regular netbooks, ultrabooks, Chromebooks, or Android tablets.  However, at about $500 for a 64gb tablet, the ThinkPad Tablet 2 comes in at a pricepoint lower than full-sized iPads and offers much more functionality including being able to run full-fledged Windows applications as well as access to 100% of websites including Flash and Java ones.

Personally, I’m planning to go paperless in my classroom next year, and this ThinkPad Tablet 2 is the device I am considering using to get me there. Going paperless doesn’t mean we can completely do away with drawing and handwriting. These are still essential tasks in the classroom, and you can’t do these sorts of tasks well with a laptop, netbook, Chromebook, or iPad. There are very few devices that come with an active digitizer pen, and the included Wacom stylus in this unit allows students to write and draw with accuracy, which could be essential for doing things like virtual worksheets, or completing MARS tasks as part of the new Common Core math curriculum.

Overall, I think the Lenovo ThinkPad Tablet 2 could be a great choice for schools and classrooms who want to have it all.  If you want to be able to easily write and draw on the device, plus run actual computer applications, plus have access to 100% of the educational websites out there — but you like the convenience of a touch-screen tablet for movies, ebooks, practice games, and photo, video, and art projects — then this is the device for you. It can meet all of those needs and will last all school day with its 10 hour battery life.
