I have been running the full version of XP SP2 since late last week. Before that I was trying out Release Candidate 2 (RC2). My primary system is a HP TC1000 TabletPC. I haven’t had any problems that I can related back to either the XP upgrade or any of the Tablet PC enhancements.

Others are apparently not so lucky. If you are having big problems, I suggest trying an inside track: http://radio.weblogs.com/0001011/2004/08/19.html#a8108.
