Planned on getting a 15" MBP but now with the 17 recently out, I really don't know what to get. With my education discounts and choosing the options of a 7200rpm HD to the 2.53 15" it is about $100 less than the 17" with the software I want. I need the laptop for video and photo editing as well as basic tasks. I have an iBook so I am used to its size portability, however I use the notebook at home primarily, usually on my lap not on a desk. Never owned a 17" and not sure exactly how big they are. Are there advantages to going with the 17" since it is not that much more. I feel 4gb of ram is plenty enough in the 15" but in 4 years will it be enough or will the 17" with up to 8gb be good? im borderline so your input would be great. Anyone with 17" would be great to hear what your input is.
