Man I love all of the conspiracy therorists who run rampant spreading crap rumors, spy ware inserted into XP when it shipped, buggy updates to force you to upgrade, blah blah blah.  The basic facts are this, Vista is an overpriced eye candy with no major benefits, period.  If you are looking to play the latest Directx 10 games, then yes you will be forced to go to Vista as Directx 10 will only be issued with Vista.  If you are looking for a preyty desktop, go to Vista or Mac.  If you have to much money on your hands, go to Vista or better yet send it to me.  If your operating system works the way you want it to and see no foreseeable reason to change before 2010, then do like the rest of us are doing, place the tip of your thumb on the tip of your nose and wiggle your fingers vigorously at Bill Gates.  If you are actually curious as to what problems you may come up against if you do go to Vista, do some research, do not come to Renederosity for answers as you will get the most assinign answers you can find, mine included.
