Hi folks, for portability reasons, I'm currently going to switch from my 13" MBP (early 2011) with i5 2,3GHz CPU, 8GB RAM an Intel 160GB SSD to the current MBA Model with 8GB RAM, 256GB SSD. Now I wonder which CPU I should choose for the MBA, the i5 or the i7? What I will use the MBA for is (from most often down to sometimes): Office (iWork & MS Office, Internet, ...) Multimedia (Youtube, iTunes music & video) Developing using Xcode Playing a little bit (f.e. Minecraft, Telltale-Games like Back to the Future, a little bit Civ V; no need for maxed out graphic settings inside the games) Sometimes Parallels 8 & Windows (for a rarely used Office-Apps or some old games like Prince of Persia Trilogy oder Star Wars: Knights of the Old Republic). Once in two or three years, I render a Movie using iMoive. So I thing that this point can be neglected. What I don't want: I don't want to buy a MBA that will be a downgrade compared to my current MBP. I don't want to buy a MBA that will get hot and raise the fan when doing the daily office work. For office work, it should be quiet (my current MBP is quiet most of the time, except when Time Machine is running or verifying the last backup - that's annoying but acceptable, but it shouldn't be worse). I don't spend a lot of money for a Mac that will be noticeable underpowered in one or to years. So take into account the things I said, what will be the better choice - will the i5 do the job fine or should I upgrade to i7? Thanks for your help, SchodMC P.S.: I hope my english is not too bad. If so - sorry for that, I'm from Germany, so english is not my native language.
