I have been lurking on this site like a madman.. I plan to purchase my first mac machine. I am looking at a macbook pro, still trying to decide whether a 13 or 15 inch screen. I do not play games nor do I have space in my apt for an external monitor. I am an amateur photographer and I will use either Aperture 3 or Photoshop (looking forward to try out Aperture) just to do basic editing (my skills are improving though). I will surf the net, use itunes etc. I do not watch movies nor do I travel often (approx 3 times a year to far destinations). This will be my only computer (I will give my current hp laptop to my fiancee). I am currently using a 16" diagonal display and I can go a bit smaller. What do you think is the best macbook pro for me?
