My pc has it and I am always having bother with it. I have heard that it is the most problem-causing, trouble-making, freezing-up, crashing windows in Microsoft history.
eg: You've only got to type something slightly too fast and everything will freeze up - and I mean freeze up - you can't even switch it off, it has to be unpluged at the wall. The volume doesn't work half the time. This is just two examples of many. It even does this after reformatting from scratch.
I'd be interested to hear if anyone else has the same.
