Hey guys, I need some help. I'm in the process of upgrading to a new computer. I currently have first-gen unibody MBP and a first-gen base 11" MBA. Looking to get myself a new computer that will last me a while. I've been looking at the retina MBP, but I'm concerned about the disk size and I don't want to spend $600 more for twice the space. So I've been looking at the 13" Air Ultimate, which I can get for the same price as a base rMBP with a bigger hard drive AND a USB superdrive. I don't care about the retina display. Most of my usage revolves around writing (Microsoft Word), graphic design (Adobe CS5 and QuarkXpress 8, probably soon to be 9). Is there anything, other than screen real estate, that I will be lacking with the 13" Air decked out to the max? I don't plan on doing much, if any, video editing. I rarely game on my Mac, but I assume that would be a major limitation of the Air over the Pro, right? Does Apple allow you to install programs on the display models in the stores? I would like to put a demo version of Quark on a 13" to make sure I won't kick myself heavily for giving up two inches of screen real estate. Let me know guys. I realize I can use external hard drives with the Pro, but I don't know if I want to constantly be connecting hard drives not sure I'm ready for that compromise.
