I really don't understand Apples drive to make the current generation of iMac even thinner than the last. It makes the heat budget your engineers have to work with even more limited. Meaning things like a sub par video card for instance. Heck, when I am using my iMac I couldn't tell you how thick it is. Nor do I care. If it were an inch thicker I wouldn't notice. And that extra space would allow a better graphics card, and maybe another hard drive in the heat budget. Whereas making it thinner, just really doesn't add anything useful at all to the product.
