Unfortunately on the Windows machine I'm on now IE6 used to crash repeatedly and take down my whole system. So, when Beta 2 of IE7 came out I made the switch. Eugh. I'm hating every minute of it - the implementation of tabbed browsing is quite practical I think, but so many other things are annoying me beyond believe. If it wasn't for my damn fingerprint reader I'd ditch IE completely - and even with that I had to reset all my passwords.
