I don't know why there isn't a standard form-factor where parts from different manufacturers can't be mix and matched. It just seems so obvious.

A fully aluminum shell with air channels drawing air from the base unit through the back of the screen (via convection) seems like a good idea too.

Another interesting design would be "vertical laptops" - like an ipad but with a fold down keyboard/pointer slab to keep it upright. That would be good to get airflow moving up through the screen vertically. There could be space between the screen slab and the processor slab for the air to rise.
