Although spared by Apple's last mobile refresh, the lowly $999 MacBook has now received a rightly deserved upgrade. You won't find a 2010 Core Mobile processor in the new spec sheet, but Apple has nevertheless swapped in a quicker Core 2 Duo, upgraded the integrated graphics chipset, and slapped on a higher battery life rating.
Specifically, Apple now includes a 2.4GHz Core 2 Duo and GeForce 320M integrated graphics, up from the previous 2.26GHz processor and GeForce 9400M IGP. The company also quotes 10 hours of battery life, up from seven for the previous MacBook revision.
The GeForce 320M debuted last month in the new 13" MacBook Pro. While Nvidia doesn't appear to list the part on its website, word around the web suggests the 320M is simply a successor to the 9400M that packs more stream processors and is manufactured using finer 40-nm lithography.
Otherwise, Apple has conserved the MacBook's polycarbonate unibody design, and it still ships the system with 2GB of DDR3 RAM, a 250GB hard drive, a slot-loading DVD burner, 802.11n Wi-Fi, Bluetooth 2.1, and the all-important giant glass touchpad. The MacBook retains its 1.08" thickness and continues to weigh in at 4.7 lbs.
