I really want to buy myself a Retina MacBook Pro. I always love having the latest and greatest. The problem is I know I won't use it to its full potential. I love how thin it is and the OS. Primary uses: college work (undeclared major, either business or CompSci), web browsing, Photoshop, gaming here and there. What should I do? Suggestions? I know it's a very expensive laptop but it'll last a good four years.
