True but...
Chrome will heat up ? it is a highly reflective surface and will not retain the heat as much as plastic will. Besides - its only the hinges and the accents around the laptop - I doubt that will affect the performance in the sun...
Carbon fibre will look cool because of the various shades - like having a b&w version of the chameleon color scheme

The laptop will be lighter and stronger and cooler.
I like the idea of backlit keys too - I wouldnt mind aluminium keys

that will look snazzy on a predominantly black laptop...
Hee hee - but out of all those ideas - the most practical one seems to be the battery pack in the carrying case
