I’m playng with the tbook power from one month now.
I can confirm the value of the keyboard.
On the Windows side is absolutely smooth. It does the ordinary work (office, web, some games) in the best way.
The android rom is full of bugs and battery hangry, but usable.
I’m happy with it.
With 200 USD You can Buy the tbook 16 pro with keyboard that has a better screen and better android rom and is more light. A little bit slow on the Windows Side. Average keyboard.
