Well, although I do have Mozilla on my system, I generally don't use it. I much prefer Opera. That being said, the new IE 7 is pretty much a year late as you say, it has tabbed browsing, etc. So far I am runnning it with Opera at the same time, and it has been stable, and is rather pretty. I do have the portable firefox on my keychain (as well as portable open office), and I am a huge fan of Open Source... Ok I forgot what my point was already....
