Hi, I just registered to MacRumors, but have been reading the forums for quite a while. I have a few thoughts on buying a new setup but can't figure out which way to go. I'm a high school student, interested in photography. Need a new setup to replace my current pretty tired PC. My first idea was to get a MBP for my main computer. Great perfomance and its portable if I need it to be. But a 15.4" laptop is too big to carry round to school every day I feel, as we have a Dell D830 in the family. Then thought about a MB, but the lack of dedicated graphics put me off buying as a main computer. Perhaps a MB for school and Photography work on location and a PC for bigger PS work and occasional gaming? How does Lightroom handle the OS difference? The ideal solution would obviously be a mac pro with MB/MBA, but that costs too much. Even MB with a 24" iMac is out of reach. Any thoughts?
