A new 2.0GHz white MacBook configuration packs an additional 512MB of RAM and 20GB of extra hard disk space, for a total of 1GB of RAM (via two 512MB SODIMMs) and 80GB of storage.
The new model retails for $1449, or $150 more than the 2.0GHz white MacBook with 512MB of RAM and a 60GB hard disk. Both configurations included Apple's SuperDrive optical disc drive.
Meanwhile, Apple has also introduced a new configuration of its black 2.0GHz MacBook, dubbed the "MacBook Ultimate."
The $1599 model includes 1GB of RAM (also via two 512MB SODIMMs), but otherwise is identical to the company's $1499 MacBook, which includes 512MB of RAM, an 80GB hard disk and SuperDrive.
The two new configurations expand Apple's MacBook offerings to five retail configurations.
