Heya guys, I know there are similar titles as mine, but I have one further question which haven't been answered. I currently have a MBP 13" 2011 with 2,3 GHz i5 and 4GB ram. Now I am upgrading to either one of the two newest MBA or MBP 13" and thought that since I don't play games on my mac and never use the optical drive, the MBA 13" would be fine. My only concern is though, since I've been using my MBP 13" 2,3 GHz i5 for almost a year now, I don't want to go back to something slower and I'm not really a tech expert, but are the speeds of these two different? Because I know the new Air might have some hardware, that my old MBP doesn't have. So please comment which one is fastest. And what if I upgraded MBA to 8 gb, would it then sort everything out? MBP 13": 2,3 GHz i5 4 GB 1333 MHz DDR3 320 GB Intel HD 3000 Or MBA 13" 1.8GHz dual-core Intel Core i5 processor Turbo Boost up to 2.8GHz 4GB memory 128GB flash storage Intel HD Graphics 4000 Help is much appreciated, thanks!
