first-time poster here hoping to get some insight from people who might have been through this decision process before. going back to business school and had been pretty set on the new macbook pro 15 but the more i look at the specs, the harder it is to make a decision. on top of that, the 17 inch screen real estate is extremely tempting. here are my usage patterns/background. - coming from work issued 15 inch Macbook Pro (2.6 ghz, 4gb ram) - power user (but no 3d modeling, gaming, etc.) - may use it to convert videos from one format to another - primary use will be large scale Excel spreadsheets and data modeling - will need to run Parallels / Fusion with Excel for some of the statistic plug-ins - will be commuting to school so i'll be bringing my laptop back and forth. but since i'm in Los Angeles - i will be driving so i won't need to lug it on public transportation. - may travel a couple times a year for job fairs, etc. i'd like to get your recommendations on best bang for the buck in terms of 15 inch models (do i REALLY need 9600?) and whether you would go for a 17 inch instead for the expanded real estate in my situation (large spreadsheets, needing to run Parallels, etc). or will the 17 inch be a pain because of its large footprint in study sessions, class, etc.) not too sure what business school life will be like so hopefully someone might be able to provide some insight.
