Hi everyone, I need some help with deciding between rMBR 15" or a MBA 13". I am starting a new career in real estate and will be using my laptop for work and personal usage. Here are some my uses: - web browsing, email, iTunes, youtube videos, minor photography and video usage for for real estate listings, client contact and profile info, using bootcamp and/or parallels for minor windows applications, and possible need for portability but I'm not quite sure how often. I plan on using my laptop daily for work either in the office, home, and on the go. The two MacBooks I am comparing are the base 15" rMBR and the 13" Macbook Air with upgraded 256ssd and 8 GB ram upgrade. I can get a fairly substantial discount on both but I would like my laptop to last at least 3-5 years before upgrading. Do you think the 15 inch rMBP is a overkill for my needs. I am leaning toward the MBA 13" but I feel like the 15" rMBP is a machine that will last me longer and be able to handle tasks that I may be using in the future. I'm just not sure that for my tasks that a "retina display" or increased cpu processor will be something I will notice for my typical computer usage. I appreciate everyone's input/advice.
