Hey, I recently bought a speck satin case off of Amazon for my Macbook Pro, but I may have run into a little problem. Although I bought the case designed for the new pro, the company instead has apparently sent the speck satin case designed for the older aluminum macbook. I have yet to receive the case, but after googling for information and coming up with nothing, I decided to ask a question here. Are there any huge differences between the two case types? The company has been very cryptic with any answers, and any help would be appreciated. Thanks!
