I love Qt, which is one reason I work for Trolltech^WQtsoftware in Nokia. and thanks to the efforts of the qt4 on maemo project Maemo Qt4, there is yet another platform/device open to any application that is created with Qt4.
Here is my old-yet-updated Gutenbrowser project on Maemo on n810. (the copyright on gutenbrowser is 1998-2008! now). I don't work on it as much as it needs. Especially now with rug rats and yard apes about.
All it took was a recompile!
Just install the scratchbox sdk for maemo. Grab the qt4 for Maemo sources, compile, install them, and your good to go! hmmm... what's next?
