Hi all, I was hoping for your opinion on this. Bestbuy is having a nice sale on the 2013 macbook airs and I've read great things about their battery life and all. I was wondering if I should upgrade from my early 2011 15-inch macbook pro. Specs: 2.2 GHz Intel core i7 quad core (Sandy Bridge...I think?) 16 GB RAM Graphics: AMD Radeon HD 6750M 1024 MB 240GB SSD I don't think I've ever really used the processor to its fullest, but I wanted a quick comparison between this processor and the new Haswell ones on the Air. Likewise with graphics, I don't do any image/video editing nor do I play any games. I do usually have a lot of tabs open though, for research papers and studying. I will primarily be using this for medical school (if I get in this cycle). Thanks in advanced for your opinions!
