> It is extremely annoying that this starry eyed experimentation is going on in the most popular Linux distro. They are basically risking the one foothold Linux has been able to make in the desktop world. If you want to experiment, you should start an experimental distro and not risk your's and Linux's one single solid success.
That is an excellent point, and one that worries me, too.
On the other hand, I'm glad that some major player in the Linux world has an interest in UI experimentation.
How to reconcile these two thoughts? Maybe what we need is another Ubuntu variant (like Kubuntu, Xubuntu, etc.) that is stuffed full of experimental ideas. And then the best ones get into the more mainline releases.
