Apple customer service is awesome! I order a new MacBook Pro last week (13" retina, i5, 2.4ghz, 8gb memory, 128gb flash) and got an email today from apple saying "You may not have heard, but we just announced the new 13-inch MacBook Pro with Retina display. Since your order has yet to ship, we automatically upgraded you to the new 13-inch MacBook Pro with Retina display." So the one I paid for was a 2.4Ghz…the upgraded new version has the Mavericks and 2.6Ghz. WooHoo. I found it cool apple sent out an email telling me this happened. Will I ever notice the difference? Probably not. But it is nice that I have a better... Thing... in my computer (yeah, trust me I'm better with cars than computers)
