What do you really want on a redesign? There are only two things I would really like to see and only one of them will benefit more people then just myself.
I was thinking about an iPod Mini/Nano like design to the MBP; one-piece aluminum with those white plastic sides for the ports on each side (getting rid of the thin gray wrap-around plastic strips...)
If anything, that's all I could've imagined to improve the already fantastic design. I don't know, maybe something a bit different. But I'm still probably going to order it.
