The most affordable laptop from Apple got a speed bump today. New features of the white MacBook include Intel Core 2 Duo CPU bumped from 2.26GHz to 2.4GHz, battery life upped up to 10 hours from 7 hours and new NVIDIA GeForce 320M graphics chip which replaces NVIDIA GeForce 9400M. The rest stays the same (2GB or 4GB RAM, 250GB, 320GB or 500GB HDD, 8 x SuperDrive).
