Bam bam so the biggest distro chooses Qt. Apparently the Gnome shit interface and toolkit isn't exactly liked by both users and developers. See stupid gnome devs, there are consequences to your actions... The fact that you choose to ignore this will be your undoing.
On the other hand, they will control Upstart, Mir (the display server) and Unity. That can be a basis for a decent stack which can be closed whenever they want.
Qt is just so much better than GTK. Every commit gets reviewed and they have a decent CI system.
Makes sense to choose it.
GNOME is RedHat's private desktop nowadays.
Unity is Ubuntu's desktop.
Cinnamon is Mint's desktop.
You can run them on other distros, but it's clear who does all the development and decides the direction.
Why don't they write their own toolkit from scratch? Call it Ut.
Really? I'd like to some sources... I really doubt this number. The work they invested into those technologies payed off while they were using them, but now they're switching to a technology they've decided is better. They have a sense of direction, even if they sometimes lack confidence.
Not really, no. QML is very flexible, and combined with Mir, if Mir works out, then they'll be able to pull this off. If Mir doesn't work out, they might be up a creek without a paddle, as the saying goes... but otherwise, this idea is just crazy enough to work.
