For the low cost MacBooks, I want to see them as the MacBook version of the iMac. Same fun colors, white bezels, white keyboards, all just like iMac. But then for on the go. Make them look fun again, just like the PowerBook G3, which was a notebook version of the colored iMacs then. I think they will sell like hot cakes. I don't need one, but if they come out, I want one.
And they would be a perfect decoy product for the white bezel haters, to divert to MacBook Air instead.
