Hello, I am seriously torn and looking to bounce ideas of someone. I welcome everyone's input! If you could be so kind as to read my situation, any and all insight would be very much appreciated! I'm debating between these 3 systems: 11" MacBook Air, i7, 8GB, 256GB 13" MacBook Air, i7, 8GB, 256GB 15" retina MacBook Pro, i7 2.6, 8GB, 256GB I recently (tragically) dropped my wonderful 2011 13" MacBook Air i7. I had often described that computer as "the best computer I've ever owned" because it was just such an awesome point where portability and elegance met performance. It never ceased to amaze me how, even with only 4 GB of RAM, I could keep Parallels 7 running Windows 7 (with 1 GB of RAM allocated) and still have the full MS office suite, Chrome, iPhoto, iTunes open and yet even with all that open I could launch X-code briskly. It never ceased to amaze me. On the other hand, I enjoy gaming. I have a dedicated gaming PC in my basement, but I have an infant at home (my first!) and I've been a very active father, and I'm almost never lucky enough to have any time to go hide in the basement and play games. My MacBook Air 2011 i7 was a dreadful companion for gaming. SC2, GW2, WoW, Civ5, Diablo 3, and just about any other game I threw at it, fell somewhere between "barely playable on minimum settings" to "unplayable." Now, I realize that the Air is NOT a gaming machine (HD3000 is not a GTX680, and ULW CPUs are not known for blazing speed). However, I have heard claims that the HD4000 is 60% faster than the HD3000, and of course 2.0 GHz Ivy Bridge i7 is faster than 1.8 GHz Sandy Bridge i7 - which could put a lot of games comfortably in the realm of "playable." The other factor is that I carry my computer to and from work every day. I work as a computer science teacher, and I do not need a huge amount of processing power for work, although I do need Parallels open all day. Not only do I carry it TO work, but I carry it between my office and classes at work, too. Portability is very important. I am leaning away from the 11" Air because of screen real estate and battery life, as well as lack of SD slot, which I use all the time, and dongles are no fun. I have always had a crush on that form factor, but it's just not practical as I will only have one laptop. The 13" Air seems to be the choice of the logical side of my brain. Fully loaded, it can game sort-of-half-decently, and it's a champ at dealing with most of my daily computing. The 15" rMBP is screaming at the emotional side of my brain. The screen alone has me infatuated. Add to that the discreet GPU, a ton of extra power, HDMI out, etc., and it's very appealing. I could see it effectively replacing my laptop AND my desktop. The size, and to a lesser extent, the weight, is what scares me away from the 15". On the other hand, my previous laptop before the Air was a 13" aluminmum MacBook which weighed about exactly the same as the 15" retina does... Money is not my main motivating factor. I have more than enough for any of these choices set aside for this purchase. Of course, extra money left over is extra money for things like a good external hard drive (512GB SSD is just too expensive!). Any and all insight is welcome! Please help my indecisive self!
