First time I will go to the 15" based model but I may not use it much for gaming. For me I just use the CS5 stuff. Rarely for photo or VDO editing. I plan to use DreamWeaver (frequent), do some programming, wanna learn writing iOS Apps, surf the net, listen to music, watch vdo, do documents, and do research. I hesitate to choose the 15 model because of these reasons. It will be my first macbook and I plan not to buy it for long time. Should I go to the 15" based model? Thanks in advance.
