I have Windows XP Pro... but thats just cause I don't care to change my comp, its pretty old. Soon Im gonna run Blackbox instead of Explorer though, just because Explorer is the truly worthless system that Windows runs.

Besides, I used to have Windows ME on my comp. And nothing can ever be worse than that.

As for Browsers, I use a mix between Firefox and Avant. Avant is run off of the same system as IE, but much safer. It's basically Firefox for people who are still too used to IE.

I'd like to buy 2 new comps eventually though, one being a Mac and one being another Windows, but thouroughly modified.
