I'm planning to buy a new laptop and there's is this offer on the previous macbook pro (the one before the March revision) I save 200 euros when I buy the previous model and as money is an issue this looks appealing. What are the big differences performance wise? I can see there is a small difference in processor speed, but that won't be really noticeable will it? Are there any other differences I'm missing? Also, what's the chance we'll see new macbooks this summer (June)? Will there be any new hardware that will make me regret my choice? I can wait till August if needed. Thanks, Asnyers.
