I've been using Linux since Slackware in 98 and CDE on Solaris before that. I hate to admit that for past 4 years, my primary OS has been win7 and OS X to do my much of my work on Linux servers. why? I need a Desktop Envirment with a consistent UI that's free of bugs.
A classic example of this is back in '08 I switched to a 16:9 monitor. Well thanks to a 6 year old bug in gnome #86382 this rendered gnome unusable for me.
Unfortunately this was also about the time KDE 4 was released. After giving a dozen other DEs a shot, I joined the the dark side.
To this day that 11 year old gnome bug remains unpatched. In an Apple or MS OS this kind of major usability issue would never make it out if Alpha never mind a "stable" release.
In the early days of Linux when It was for hackers by hackers this was acceptable and expected. They want to add cool features not fix bugs. Fine.
But now there's some serious money in Linux. Between Redhat and Ubuntu How the Linux Desktop can remain in such a sorry state. And I fail to see how another fork will make this situation any better.
Sorry for any grammar errors/typos, this message was written on my phone in topically useless all hands meeting.
