Here's one, generally these apps will be installable on windows, I think VLC is also a Qt app (well just the skin)
The Ovi thing is for devs who need to make cash and users who like the simplicity of an app store. I hope it doesn't become a restriction tho.
Edit: Confirmed, VLC is actually a Qt app, most ppl are already using Qt apps extensively.
Thats why I say if the Qt strategy works no one will remember app stores, since even windows and Mac apps will be written in Qt for instant Cross Platform compatibly.
Currently Android/iOS/BBOS might not have a Qt platform port like they do for java and java apps, but in time they all will esp if nokia executes correctly.
devs will only need to code once and apps will compile and run natively at each platforms highest performance (or close enough once the platform has been optimized to run Qt apps.
So no more app store here and there, just download an app and use.
