Hi all. I just read a guide from this macrumors guide-wiki where it stated that the 13" is more for checking emails and surfing. Ill be doing alot of programming and maybe some editing of videos and images(not very demanding though. Images not in raw and video not of great quality), mostly programming. I want things to run smooth, its one of the main reasons for me to invest that much money in a new computer. Is the 13" sufficent for my demands or will it get tired and slow when i start doing things with netbeans in java etc? In a not very farfetched future there might also be som parallel and graphics-programming. I really like the size of the 13" but i would hate to buy one and things start to slow down as it has with my homePC(wich isnt built of the best hardware though). I will do alot of my work when traveling, i will cary it with me to school and other things like this. The 15" just look so big! Any advice?
