I think the black keyboard is the ugliest part of the MBA's design. There's cool retro, but it's not the TiBook's color scheme. Granted, I think they should have made a black-key aluminum desktop keyboard like this (and a black mightymouse) to go with the new iMac's color scheme. However, they should have made the MBA keys aluminum-colored or at least white, but preferrably aluminum. Having an aluminum body, black keyboard, and white cords is just straying too far from my minimalist color taste. Here's hoping the next MBP keeps aluminum colored keys (I doubt it, but fingers crossed).
