Hey guys! My working horse at home is a 27" iMac with SSD, 32GB etc. I'd like to get something portable to carry with me. Whats the "better" addition to this setup? Gonna use it for surfing, writing, powerpoint and some photo-work (main post production @ 27"). I'd say the 11" would be great for this but I dont like the battery life (3-4 hours) in comparison to the 13" and the big big frame on the 11". This looks really ugly :X .... You have a similar setup? What would you do? 11" - 4GB - 128GB or 13" - 4GB - 128 GB?
