hey guys the old white macbook used to cost $1300 for the 2.4 GHz models but now the new alu macbooks have quite a significant price hike and a processor speed decrease. The new macbooks are priced at $1299 but we can only get a 2GHz processor. I know that there are extra costs for the new GPUs but still apple should not remove that extra speed from the processor. Anyway is 0.4GHz significant in the operating speed of a laptop?
