Curiously enough, both of those opinions were expressed here in the MacRumors forum and by more than one poster - just one of those things don't have the time and energy to argure argue against....
Because it is true. You cannot argue against the fact that Apple laptops did not in fact come in white until the iBook clamshells and entirely-white iBooks.
I loved the PowerBook G3s. When Apple released the silver titanium powerbook g4s I was disappointed. Somewhere around then and up until the blackbook I've had both iBooks and PowerBooks and I've never liked them. With the blackbook, I feel like I'm in heaven because I finally have a laptop that's in a color I wanted. And when you don't have much variety in color (remember beige vs. fruity iMac G3s back in the 90s? well, it felt like a modern day beige with not much of a choice, Apple's computers being all white or silver) you think of more drastic things to do, like expensive or DIY paint jobs. I had actually removed the paint on the casing on my iBook G3 to paint it black for my iBook G4 to swap after the warranty ran out..but the blackbook was released
And hey, look at what Dell's doing right now..dumb ads about colored laptops, because they finally got what Apple was doing back in 1996 (well, and subsequently ditched in favor of black/white/silver)..."A democrat chose red"..."a vegan didn't choose green" or something along those lines...
