I am interested in purchasing a 15" macbook pro (unless someone has a compelling reason why a 17" would be better suited to my needs). My primary concern is battery life and capacity decay over time. This computer will be used to produce photo and video content primarily at football games, and need the battery to last about 4 hours (absolutely no less than 3) under intense and constant use to include some pre/post-game content. My needs from a laptop: Store 21mp RAW photos in real time Store 1080p video in real time Edit live 480i video feed from 3 cameras, output as low-res stream to web None of these tasks would be running concurrently, but I need a computer that is capable of doing each. Portability is also of great concern, which is why I am leaning so heavily toward a 15" with a matte display (allowing easier use outdoors, better photo color for editing, and removing the glass weight). This is what I'm considering: 15" uMBP 2.8GHz 8GB RAM 500GB HD @ 7200 rpm Antiglare option Getting the 3.06GHz processor is also an option, and could be better-suited to my performance needs, but I'm not sure how badly that would cut into battery time. Any thoughts or advice on this is much appreciated. Thanks!
