I run Windows XP Professional at home & @ work. Do not plan to upgrade to Vista anytime soon. I will convert to Linux first… IE7 no big deal. I have deactivated many of it’s features so it basically runs similar to IE6. I also have FireFox 2.0, and like it well, especially since it accepts proxy addresses. However, there are things that IE can do that FF can’t, and vice versa, so I keep them both handy.
