pc user here, currently have a 17" laptop that weighs 8.5 pounds! time to upgrade, pretty convinced about getting a mac. not a student, don't travel with my laptop have an android for the internet on the go. the 17" MBP costs a lot more than the 13/15" models. my current 17" is a desktop replacement which i use about 50% at my desk and 50% couch/bed/kitchen table. i'm a relatively serious photography hobbiest but not a pro and no aspirations. what do you reccomend? i can't make up my friggin mind anyone here face a similar dilemma once upon a time?
