>BTW: I keep seeing people talk about this hybrid concept but I have yet to see a UI toolkit that trivially scales up and down between phone/desktop. It mostly seems to involve a lot of compromises and a lot of extra work.

Except I don't care about desktopified android/iOS/windows phone apps. All I want is to run my already existing open source desktop linux applications. Chroot on android doesn't have hardware acceleration and you have to use VNC for anything graphical.
