I was, of course, just reading an AppleInsider article on the forthcoming Macbooks which was discussing colors and configurations. They suggest that in order to simplify SKUs and inventory with various colors, they may offer only two hardware configurations: better and best models. (Which leads me to ask, better than what? The previous iBooks that haven't been updated for years?)
If this is the case, I'm guessing the "better model" will go for $1,000 and the "best" model for $1,500, giving consumers $500 between each model.
I have to admit that getting a core duo Apple laptop for a grand seems like a pretty sweet deal, as long as they don't go completely chincy on the other hardware specs. (C'mon, a 32 MB video card in the original Mac Minis?)
