IE7 isn't that bad, it's rather good dont' go overcritical on it, on its own its a decent browser. (don't you love how being a moderate makes you seems like you flip flop when the other guy does..)
Why so? IE is integrated to the OS so malicious programs can corrupt your OS through IE. A lot of security holes too. EDIT: Damn, I did not see the 'not'... Jeez gettin old already...
it'll be good once Vista comes around, ie won't be intergrated in the OS so you don't gotta deal with it being a pest thats the biggest pro i got about Vista (a tad off topic but still fits)
Lol.. I'm a FireFox user too.. I mean, I used IE back in the day, but that was before there was any decent competitors to it. In comparison, IE blows goats compared to FF. Cant make any comments about Opera though, as I've never used it
