I like the laptop versions that have screens which can fold around 360 degrees to act like tablets. The keyboard deactivates and you get an Android-style onscreen one when you do, but I think some people don't like that because it does mean that your screen will be fingerprint-y. But personally, I also like having a touch screen, especially since a bunch of Android apps run natively now.
I have the C100 Flip right now, which I like a lot. It has a Cortex-A17 which doesn't have trouble running a bunch of tools I use like KiCAD, Arduino, etc. but I wouldn't use it for 3D modeling or other intensive tasks. The resolution is also a bit low at 1280x800.
Keyboards that don't bend? What makes do you recommend?
