Theres lots of super thin digital cameras, an inch thin or less (coolpix, cybershot, etc). An iphone, which has a better screen, more capability and cpu power than a camera is extremely thin, what 'cooling gap'? Are you saying that the thickness of the sensor goes up as sensor size increases? And theres plenty of $$ cameras with no removable lens, fuji x100 series, Sony RX1, leica Q, etc, like you linked.
