Hi there. I am looking to replace my iMac for a MacBookPro plus an external display. I am looking for portability but also for power as I do some photo work in PS with RAW files and have a quite large iTunes library (about 150gb). I would love to have the high end 13" MacBookPro rather than the 15" because of the size and weight. These are my actual iMac's specs: 2.0Ghz Core 2 Duo 2GB RAM ATI Radeon HD 2400 128MB So the question is: Would a 13" high end MacBookPro suit my needs? Is the graphic card's shared memory an issue here? Thanks everybody!
