Python and Qt in 30 mins
There is much talk and speaculaton about the future of the N900 and indeed Maemo. I see the announcement for MeeGo as a positive thing that will bring many developers over to our neck of the woods. Most of the applications developed in Qt can and will be made available to the N900. What ever becomes of Maemo6 whether it will be compatable or not seems to be an issue of great debate.
All I can tell you is the only device to openly demostrate Maemo 6/Harmattan is the N900 at the moment so that at least proves concept. There are many developers in this community who make it their business to bring the seemingly unachievable to the general end user. Have a read round here.
Buzz words for searches.
Harmattan
Maemo6
MeeGo
