I'm planning on picking up a brand new MBA, specifically for everyday university use. Given the work involved, the bulk of my work will be focused on word processing, web browsing, email, mind mapping, and listening to music throughout (primarily online, di.fm, Soma, Pandora, YouTube, etc). I'm leaning toward the 13", 1.7GHz i5, 4GB, 128GB SSD over the 11" variants as I've read here that the 13": -Has a slightly longer battery life -Has a slightly higher resolution -Many have mentioned how the 13" is easier to see than the 11", specifically in regard to word processing over long periods of use. So, for a student who is carting it around in a Timbuk2 messenger bag, working primarily in a word processor, web browser and email client while listening to music...is the 13 the better choice? Am I overlooking something elementary that the 11 would be better suited for? Any constructive thoughts are welcome.
