Read carefully to what i wrote. I said iti s no Use for us. it is meant for Developers.
They need it for developing apps using Qt 4.7 and its great eye-candy features, and you need it to run those apps.
So it's a release for users, too, as its a requirement for running Qt 4.7 apps.
I've observed three nice changes:
1 the yellow volume graphics (when turning sound up/down) does not seem to make the N900 stutter anymore
2 portrait to landscape (and reverse) seems much snappier
3 internet stations seems to work much better (less dropouts)
I thought that was what PR1.2 and Qt 4.6 was all about
Nokia tore up their operating system plans last week, doing away with Symbian v4 and going to shorter release cycles.
One of the consequences is picking a single shared runtime across all their future smart phones. And that's QT4.7 (etc.), and honestly they'll stick with it for more than 6 months this time...
