Linux desktop has already arrived for me. All the apps and utilities I need is there, all installable via apt. It's not a Linux problem anymore when the hardware manufacturers won't support it.

GNOME is nice, KDE is nice, and we have other options for people that don't like the two previous one. The issue we have now is walled garden, when some proprietary software won't support standards and even their own file format.

I'm in a MS centric business and am in the middle of setting up a Linux MOE solution for it.. this is winning in my mind.
