Re: physical keyboard
Android apps should support custom screen formats, but they don't. The only reasonable format if you're using common Android apps is a portrait screen.
It is possible to do split screen, but this then squashes the app making it fairly unusable
I really must get around to tweaking the non pocket Titan to do the split screen horizontally rather than vertically, because that might be a decent work around. It does have 'mini mode' but that wastes a huge amount of screen estate.
Also, having compared the Pro 1 to the Titan, the Titan keyboard is generally an improvement. It lacks arrow keys and a separate numeric keypad, but is otherwise more pleasant to type on.
