I ended up buying the upper model 13 inch pro. I probably should have purchased the lower end 15inch but didn't really think I needed that much since my old computer wasn't that much. I am going to get the extra 4 gb of ram in the future so I will have 8 when all is said and done. So now the question is, should I purchase the apple wireless external keyboard and mouse or do you think there is some third party brand that is better. I use the thunderbolt display for my monitor so I have a nice 27inch HD monitor, but am having trouble getting use to the tap pad on the pro and using it for selections and different stuff with photoshop. Thanks for your input everyone!
