Hey all, I just ordered the baseline 13" rMBP. I am currently running on a Mid-2009 13" 2.53GHz Intel Core 2 Duo with 4GB of RAM and a 1TB Hard drive (I'm going to pass this one to my wife as she's running on a plastic 2006 Macbook that can't go past Snow Leopard). I understand the Haswell's will be better battery life, but my battery lasts maybe an hour with this computer and that's fine for me. What about performance? Am I going to miss out on a huge performance increase? Also, I'm a bit upset that you can't change out the RAM or the Hard Drive. How do I compensate for missing out on my huge hard drive? I got the 128GB SSD. Where do I store my iTunes library? Luckily I have iTunes match. Also, what about my iPhoto library? I do have a Time Capsule as well, but if I store it there, then I won't have a backup for that. I guess I should have considered that. My other colleagues got the Non-Retina macbook pro with the same specs for the same price, however, I think they can change the Hard Drive and the RAM. Thanks everyone, can't wait to get a new machine. Oh and what are the chances I'll be entitled to OS Mavericks upgrade for free?
