There were rumors back in the beginning of October said that Apple was going to update the MacBook around the beginning of November.
And as usual, this promptly happened, and the first of November Apple quietly unveiled the new specs of the MacBook:
same price, but new processor 2.2Ghz based on Santa Rosa and the GMA X3100 graphic card. All the other specs remain unchanged.
Now it's really time to buy my new laptop.
