Proof that Apple has anorexia: 5mm thin on the outer edge of the all-in-one computer and monitor. Thinner than a lot of monitor-only's everywhere else. What is the purpose? Who would not trade a thicker stationary monitor for better upgrade-ability and/or a cheaper price? Look behind your monitor - odds are, it's just a bunch of empty space behind it on your desk. I would love to be a little bird on the wall in the Apple strategy meetings where they decided that iMacs need to be that thin. I still have an old iMac G3 kicking around from 1999. It's over a foot deep, just takes up the empty space behind the screen on the desk - no big deal.
