What?
Duh, it's either a clamshell rectangle with screen and keyboard or a box that a screen & keyboard plugs into.
If it is portable it shouldn't be too heavy and the big innovation would be 8 hours + life instead of approximately 3 to 4 we have had for ten years.
The screen and keyboard shouldn't be shiny.
The keyboard should not get jammed with hair and crumbs.
It should be reliable and fast enough (1/10th second response worst case to any action).
It should have all the I/O required and spaced such that something in one aperture doesn't block the neighbour.
Stuff like ultra thin, alloy casing, carbon fibre, funky translucent plastic or what ever is irrelevant unless it is needed for above.
He is clueless.
