Carolyn, Windows XP does a great job. If Windows Vista hadn't come preloaded on my last laptop, I would have chose to stay with XP. Service pack Two pretty much corrected all the initial problems XP had. It is now a good operating system. Windows Vista and Windows 7 have some quirks I don't like. I think I just like the minimalist approach to operating systems. I wish google would come out with the droid system for laptops.
