I keep wondering. Is there even a decent FOSS tablet (as opposed to desktop) environment? There are plenty of reasons why iPads and Macs have vastly different UIs. KDE seems strictly desktop-focused. Gnome seems to be pulling in both directions, but a considerable amount of functionality is only accessible thru crammed menus and buttons.

What about the apps? I've heard really good things about Krita, but what's the killer app?
