Apple updated its white plastic polycarbonate MacBook to more closely align with its new unibody MacBooks. So for the same $999 you now get that newer generation 2.0GHz Core 2 Duo processor with faster 1,066MHz frontside bus, 2GB of 667MHz DDR2 SDRAM memory standard (up from 1GB), and integrated NVIDIA GeForce 9400M graphics. Whitey is still stuck with DDR2 SDRAM though, not the speedier DDR3 found in the unibodies. Disk drive and other specs (including Firewire 400) appear to be the same. Bluetooth received a bump from 2.0 to 2.1 as well.
