So I thought that I was going to buy a 13" MBP with Snow Leopard for sure in September, but now I hear of these new Arrandale chips. I new technology is a game of having or waiting, and of course having is the best part, but from what I see these Arrandale chips are supposed to be a lot more revolutionary than what Apple improved over during WWDC (faster, more battery life, cheaper). Integrated GPU, more efficient, etc. Has Apple always released Macbooks at the WWDC, or do they also have a history of releasing them at CES?
