Hi... I am not able to decide whether I should go with Macbook Air 1.8GHz (Turbo boost to 2.8) intel i5 ivy bridge with 4GB ram, 256 ssd or Macbook Pro 2.5Ghz (Turbo boost to 3.1) intel i5 ivy bridge with 4GB ram, 256 ssd (as they both just cost the same and I have a max budget of $1500) I need it mostly for my college work like making presentations, word, etc I also use lot of excel for running regressions and data management but for advanced statistical work I use Stata. I might also be using SAS next year. I am also into photography and use Adobe Lightroom 4 and Photoshop CS5 I mostly do editing and stuff on my desktop but when I am out of town, I need a laptop which I can use for light editing and for that I'll be using Lightroom a lot. Other then this I mostly watch movies and do casual gaming like counter stike, nfs, etc So my major concern is Lightroom... that it should work smoothly and without much lag. It should not happen that I am left waiting for it to complete tiny tasks like colour correction, contrast, spot removal, sharpening, etc. Other than this excel and powerpoint should also run smoothly. I am basically looking for a laptop which is portable... yet powerful enough to meet the above needs!! So if these 2 machines will perform equivalently, then portability and weight matters to me and I'll go with Macbook Air... But if there is a huge performance difference between the two then I'll stick to Macbook Pro. What do you suggest? Kindly also tell... is it true that Macbook Pro display is better than Macbook Air's?
