I just got my new iMac today. 20 incher 2.4ghz. I just wanted to put my review of the new keyboard out there. I LOVE IT. It is by far the best keyboard I have ever used. So, if you are worried about the new keyboard, don't be. IMHO. Also, the mighty mouse blows. Is that thing made of paper mache or what? Thank goodness I had a wireless Logitech laying around.
