Hey, i am planning to buy an 2011 13" MBA for college use. While configuring it on the Apple store i noticed that there is an i7 option for the 256 SSD, but not for the 128. Is there any way to get an 128 GB version with i7? The processor upgrade is very cheap, but the SSD upgrade is not affordable for me. The 128 MBA would cost me about 1170, the 256 with i7 about 1500 . I don't really need the extra HD space as i have plenty on my Imac and external drives, but i'm afraid the i5 could be to slow for my needs. How do the i5 and i7 compare performance wise, is it a big difference? I will do some programming, audio recording with logic (as soon as a TB-Firewire adapter is out), designing (Adobe and Macromedia programs), some 3d modeling and animation and office stuff. I will use the MB at college, at home i have a 27" 2011 Imac. Will the base 13" with i5 be enough for my needs? Should i consider a MBP instead? For the best mix of portability and comfort i absolutely want a 13", no 15" or 11". Thanks for your answers.
