I've been for 6 months an Air-only user (both 11/13) and now that I am back with a 13" Pro I've been thinking about it.. While I surely lost the portability (in fact the "special" portability) I am somehow happy with my Pro right now. I am happy that my fans don't run crazy every now and then, I am happy with the more "deep" keyboard and above all, I think I missed the feeling of having a "real machine", similar to the feeling when you're holding a good build phone and not some super ultra slim one. By no means I'm ditching the Air now, even now I am convinced that it is a wonderful machine, but I don't think it's just ready yet to become a Pro or vice-versa. The heating issues ARE still there, it doesn't run like a toaster but it's still increasing a bit when a Pro doesn't. I'm not comparing the Air with the Pro. My point is that I am not sure if the Pro is ready yet to be a powerful and slim machine in the same time without worries.. Just look at the 13" 2011 Pro and even the 15" sometimes running significally hot (indeed a lot more compared with the 2010 model). About the ODD, I don't know about you, but even in a digital-download era, music stores still sell CDs, magazines still ship DVDs, movies are still being released in DVD/BluRay. Sure, in these 6 months I had no need for a disc, not even once, but I am sure it will come someday.. I think, that ODD is maybe technically not needed anymore, but socially there is still demand for it. We can ditch the DVD Home Cinemas this way as well.. And let's face it, in this moment the Pro is still thinner than most (if not all) other notebooks.
