Like falling dominos, the 13.3-inch MacBook is the next in line to cast aside the Core Duo chip and gear up with the Core 2 Duo processor.
A nice holiday season surprise is that not only are the prices for the three MacBook models unchanged, the specifications have been bumped up, making these portables even more attractive to your wallet. The base model stayed unaltered except for a processor upgrade to the equivalent Core 2 Duo chip. The midrange laptop and high-end black model have had memory increased to 1GB and the optical drive upgraded to a double-layer SuperDrive. Their harddisks have also been increased to 80GB and 120GB, respectively.
According to Apple, the new units should show up to a 25 percent performance increase from the previous generation. The new MacBooks are available for order at Apple's online store and take three to five business days for delivery.
