the plan was that Nokia should rewrite meego-handset ui using qt-components but codebase has been closed since january then Intel came up with meego-ux instead so it seems the community prefer than one now cause Nokia doesnt seems too get the damn qt-components code open again. http://labs.qt.nokia.com/2011/01/31/well-be-right-back/ techprev is avaible for symbian I asked for meego but no good answer so far except Kate said in april (in mailimglist) that it will "soon" be available....
We are looking into including tablet-based apps or the whole UI, and you can try the progress any time since we are building images for those configurations also. This is where we would need help also.
