I just got an Apple Macbook 13 inch that was released back in '08, and I haven't opened it because the new 13 inch Macbook, now dubbed the Macbook Pro 13 inch, has been released a few days ago and is cheaper and has more features. If I haven't opened my laptop, and bring it to my Apple Store I bought it at would I be able to either exchange it for the new one, or get my money back to then use to buy a new one? Thanks for any answers!!
