I have been using IE7 since the debacle of trying out Windows Vista RC1 and tbh I really like it. Mainly because it works quickly, its blocking everything I want blocked, it plays everything I need to it play, and well thats all I can ask for in a browser.
So I have no intention in going back to firefox which was starting to crash constantly and was slow at loading pages, so its all good, with the release as an automatic update.
