My point is just that the cpu, mobo, battery, and drives of a laptop could easily fit in 1/10th the size of a MacBook sans monitor & keyboard.

I'm told the next generation of NVidia chips are going to be amazing. A friend is working in high end audio, making a "iphone on steroids" touch-screen remote for the system. The tablet will have full 3D graphics for an 8" screen with half the thickness of an iphone. With a tiny folding keyboard, solid state storage, and some sacrifices on batter life for size, hardware designers should be able to put an ultra-ultra-portable on the market within a year or two.

Asus Eee looks great for that, but I'm with you, a thin Macbook makes me feel happy :-)
