>>482898041. battery life with normal usage (not planning on playing games)
I get 1-2 days
2. any sw problems I should be aware? lags? hanging for no reason?
While android apps can run a bit slow on it, the OS always feels snappy
3. anyone touched the TOHKBD? is it worth it?
Nope. I did 3D print a new back which is pretty cool
4. app development compared with android development
It's extremely easy to get started with the SDK, QML works a lot like setting up android layouts in xml, and so far I've only been programming in javascript although supposedly C++ is an option
