I'll try to remove it and be sure that everything is relative.
And I'll let you know ;)

I'm not only writing here.
I'm being posting on Twitter like hell.
I'm practically stalking @hhartz about the Maemo 5 builds.
What else should I do more? :P

Anyway, jokes aside QML is so promising that I decided to develop my current
project on it. I hope I can rely on the fact that, but early H2 I'm going to
have something stable.
It will work as a strong advantage the knowledge of QML: UI wise I think
it's the way forward to bring Qt to the Cocoa/Cocoa-touch level... and
actually way beyond! ;)
