For the browser being laggy... I think it has something to do with the way 2.0.1 renders pictures. Before update, when you scrolled, the pics would revert to a sliiiightly lower quality (without antialiasing) until the screen stopped moving, at which point the picture would go back to the antialiased version. In the new version, it keeps the antialiasing on during the scroll which would require more processing power... just what I've noticed. Oh, and it's not just the browser... it's everything using html... emails, facebook, etc...
