The current iMac design is really great; there is nothing wrong with bezels on a desktop monitor, what harm do they do? The chin is a good place for the apple logo, it also raises the screen so you don't need a stupidly tall looking wobbly stand and it allows you to change the screen angle without touching the screen. The current iMac stand is very solid; and it almost squats on it; in an extremely stable way. The memory is simple to upgrade, it slides out from its own little door; and the curved shape overall is very stylish in a slightly retro way. The ports on the back are the only pain you need to add a hub. The mock ups of the new iMac that have been shown look like a rather boring monitor.
