Hey, I'm finally ready to press the buy now button on the MBP. As much as I want to wait for the new MBP redesign, I really want a MBP for school in September. It's so inconvenient not having a laptop on campus. I'll survive when the redesign comes out I guess, or I'll do my best to sell for a decent price. Some quick questions: 1. I want a 13" for the increased portability, however should I do the i5 2.3ghz or 2.7ghz i7? Is it worth the $300 price increase? (I know it includes more HD space too). I don't plan to do anything other than email, web, internet, etc. But I don't want to ever have an issue with speed either. Can you notice a difference between the 2 processors? 2. Does anyone use one of those speck seethru cases and a sleeve? Just wondering if you have a case on it if it'll still fit in the sleeve? 3. I will sometimes be using an external display, and mouse/keyboard. Would this be the best thing to use for ventilation, etc. for storing the Macbook in that configuration?: http://store.apple.com/ca/product/H6364?mco=MjI4ODAxMzA Thanks so much!
