I recently converted my system to KDE 4, because some software I wanted to run required it. I'm less than impressed: it seems the developers decided to break a bunch of things that were not broken, in the name of progress. That's the sort of thing I expect from commercial operations who need to justify every new version as new and different; I hope for more stability from free software. Here are some notes on making the new system livable.
