I'm interested in selling my MBP 13" (2009) for a MBP 15" (2007-2008). The reason why I'm interested is because I'd like to have more screen space when I'm working with Final Cut Pro, Photoshop, and multitasking. I know I'll be missing out on the multi-touch trackpad and a better build if I were to make the switch, but I do not mind these factors. What's your guys' thoughts? I need to hear whether or not this choice would be a foolish one or an okay one to go with.
