I use XP Pro and have no problems with it.. I agree that some of the network configuration "wizards" are dumb, but that hasn't changed from 95.. Stability wise, it's fine.. I occasionally get an explorer hang and killing it takes my desktop as well (nothing new) but that's only when I get impatient and kill the tasks.. The least attractive function is the window that pops up when you insert a CDR, asking you what you want to do whenever you insert that disk.
