It's only thin at the edges. It's actually as thick as the older model towards the center of the machine....the only thin parts are around the bezel edges where it tapers off. I had the idea that Apple that pioneered this revolutionary new design which was a 5mm thick panel, using thin drives and flash memory to reduce size. It's all really a gimmick, the thing is not thin. The 2011 iMac is still a helluva machine, and the new "design" is not much to brag about.
