I read the stuff about it in their site, and I decided to wait a little bit till they've ironed out some of the bugs. It keep on saying stuff that read to me as meaning "this bit won't work quite right, but we'll be sorting it out soon".

So I think I'll stick with Firefox 1.5 for a little while. (Only time I have used Internet Explorer recently was for 30 seconds or so when I had to set my new computer up and needed to download Firefox.)
