While the underlying OS of Ubuntu is solid, it's desktop / windowing system is crap.  And it looks very unfinished as well (maybe that's an understatement, design people call it plain ugly).

Ubuntu has a LOOOONG way to go if they want to target the desktop market...

Problem is, they're playing catch-up all the time, and history should have learned them that playing catch-up with Microsoft is a very bad idea / waste of time.

I think they should forget the whole desktop thing and focus on server and embedded applications.
