The new laptops are now available from Apple retail stores, product resellers and the company's online store.
The new consumer laptops, all of which are an inch thick and have a 13.3-inch display with 1280x800-pixel wide-screen resolution, are available in three models: white with the option of 2GHz or 2.16GHz Intel Core 2 Duo processors, or black with the faster processor.
All three models are equipped with 1GB of RAM that can be expanded to 2GB of RAM. They also have built-in iSight video cameras, AirPort Extreme wireless cards capable of 802.11n wireless networking, two USB 2.0 ports and one FireWire port.
The lower-end white MacBook, with a starting price of $1,099, comes with an 80GB hard drive; its 2.16GHz counterpart, which has a 120GB hard drive and a faster, double-layer support 8x SuperDrive DVD drive, costs $1,299. The black MacBook, identical to the faster white MacBook except for the color and a beefed-up 160GB hard drive, is priced at $1,499.
Apple also manufactures higher-end MacBook Pro laptops, which did not receive updates this week.
As reported on CNET's Crave blog on Monday morning, the new MacBooks do not include several features rumored to be included in their next iterations. Among those features are Intel "Santa Rosa" processors, solid-state hard drives and LED-backlit displays.
