Yes, I don't see a problem with that. Qt Mobility is 4.6 material. 4.6 for Maemo is not out yet, so it's no wonder Qt Mobility is not functionally complete/missing. As long as Nokia seriously means 'we're working on it', it's OK. Realistically it's still way better than starting to learn GObject/GTK stuff and then realize it's anybody's guess what of that API/those libs will survive in Maemo 6.
