My theory is that the current low end MacBook (white plastic) will only be around for a short while. They maybe had extra parts or stock and needed to get rid of it. If that's true, I think the new 2.0GHz aluminium MacBook will become the base model once the old plastic one is gone and they'll drop the price to $1,099. Then they will have 3 aluminium MacBooks and no plastic ones. I'm not sure if the current 2.4GHz model will become the middle model or the top model. If this is what's going to happen, I wonder how long it will take. It may be fairly soon if they're just trying to get rid of some excess parts/stock, possibly even before Christmas. Do you think this is what will happen? Is it worth waiting?
