the fiber optic mods are nothing like the illuminated keyboard in powerbooks, and they're more cosmetic than utilitarian (your eyes can much more readily identify the pb keys than ones that are entirely glowing). unfortunately, there is currently no way to get a real one in there. i'll bet apple eventually puts the illuminated board in all PBs but not in iBooks, as a "luxury" distinction.
on a sidenote, i wish they'd bring back the italian leather wrist rests. on a PB with the keyboard, it would be stunning indulgence...
