Apple wireless keyboard key color...

once i purchase my 11" air, i plan to do a desktop setup with it, buying an external display, apple keyboard, trackpad, and speakers.

i am sure a lot of you are like me, and like our apple products spotless. i feel like the white keys would wear and maybe show some discoloring. anyone feel apple will roll out with new keyboards sporting black keys like the laptops?

if not, do they make keyboard covers that are sleek enough as to not take away from the design of the keyboard? i know they make them for the laptops, just not sure about the keyboard accessory alone.
