Apple recently added two new retail configurations to its MacBook line of consumer notebooks, both of which are now available at most of the company’s stores. 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 USD 1449, or USD 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’.
