I've had IE 6 since it was in beta stages, and since the second release of the beta, I've been extremely pleased with it. It hasn't crashed yet on this comp (had for... almost a month now?)... but really, when it comes down to it, I can't find any differences between this and previous versions except the icon and an option to delete all the cookies. Hmm.
Well, I recommend getting it, as it is based on XP technology, so should be stable.
