| If your system came with Vista, or you're buying or building a new one before Windows 7 comes out this fall, you should be running Vista (and 64-bit Vista at that -- RAM is too cheap not to have 4GB+, if you have 4GB+ you need 64-bit to see all of it in desktop Windows, and Vista x64 drivers are much more readily available than XP x64 drivers) unless you have hardware or software that absolutely won't run there. Running eight year old operating systems is a Bad Thing for all sorts of reasons.
On the other hand, OS upgrades are a pain, and generally not worth the effort. If you replace computers every 3-4 years anyway, just stick with what you've got until you buy/build a new box.
