On a side note, if you are still considering whether or not to upgrade to Windows 7, I do highly recommend it. As a previous Vista user, all I can say is it’s a lot better and much less of a hassle. Trying to search for anything in Vista was pretty much useless, but rest assured that Win7 has fixed a lot of these issues. Long story short, Win7 is what Vista should have been.
