Qt already works in all platforms. Why would anyone wrap the Qt SDK in a layer of cheat?!
Are they trying to fork Qt? They've already patched it to run their crappy display server, how much crap have they added to Qt so it doesn't compile to windows and mac?
Every single piece of cheat they create only runs on Ubuntu and they all run like cheat. Unity, Mir, Ubuntu One, Software Center, Compiz/unity, Launchpad...
BTW, I've just discovered I can't install Ubuntu One in other distros. And that crap runs like cheat on Android and Windows.
