Like people have said, if u were using 98 then an upgrade would be well worth it, but since u already use 2000 and it works fine for you then i see no reason to upgrade to XP... both are in most cases as good as the next, XP is a little more newbie friendly but i'm sure u'r already used to 2000 by now

Perhaps a very important thing to consider since its getting close now, is 64bit computing...

My point is that if u plan on upgrading u'r PC to 64bit soon there's no point buying any 32bit OS.
