I know all the rumors are that these are coming next month but I can't wait that long and I need a ODD and an external is not practical for me. This will be my fourth mac so I am not really a newbie. I need a computer and I just sold my iMac. On macmall.com these two models are pretty close to the same price. 2.7 is ~$100 more. (I know that is the older version.) Here are my questions: Are there any hardware differences that I am missing? Is the i5 vs the i7 worth the $100 more? Will I notice the difference? Would buying the 2.7 ghz be worth the extra money when (read if, I still have my powerbook from 2004) I decide to sell? My computer is mostly used for Microsoft Office, burning DVDs and editing a few movies a year. I am by no means a heavy user. Just need someones advice, I have annoyed all my mac friends to death with my conundrum.
