I've been using IE8 for about a month without any problems. It is faster, as they tout it to be. However, I had a scare when I first installed it. Man... was it EVER SLOW. I decided that I didn't like it and tried to re-install IE7 but couldn't do it... got the "a newer version has been detected" blah blah message. For some reason I decided to reboot... and things were normal again. I really can't find anything wrong with it.
