I've been using a 24" iMac for a couple of months now... I previously used a G5 20" iMac. This is a big improvement.... We couldn't really justify the cost of a Mac pro at this point.... The only things I'd wish for, Apple improved on the latest iMac..... I'm also using the wireless Apple keyboard and mouse and loving them both.... The mouse is glitchy from time to time, but otherwise works well for me... I love that my iMac sits on my desk with only the power cord running to it (Wireless N is awesome) ...
