Maemo is okay, and people should encourage its use
a) yes, devels who made Maemo apps using GTK+ will bitch that they have to redo them to use Qt. Too bad. So sorry.
b) You clowns should be supporting Maemo. In fact, you should be encouraging its use on other ARM-based portable devices. The world desperately needs more handheld computers that don't suck down and waste loads of power, and are open-source (meaning, not whatever the iPhone runs, and not the garbage called Windows Mobile).
Maemo 5. for all its peculiarities, has a track record and a good history of reliability on Nokia tablets. It's done a poor job of attracting independent app developers, because of the horrible devel infrastructure. Nokia appears to be trying to change that.
Android? WebOS? Both crippled. Don't make me laugh.
