How's the UI of android in landscape? In iOS it's terrible, dozen of apps are portrait-only and if they are landscape the UI elements get utterly big. Bought BT slider for my workphone but thing is, almost don't use it because of the clumsy UI and integration.

N900 is still my device of choice for typing mails. Too bad it doesn't support whatsapp anymore, because too much communication happen through whatsapp.
