New to the site... looked like a great source for some information. I have a ~7 year old MBP that is slowly beginning to die (may she RIP). I am looking to get a replacement, but have been torn between the Air, Retina Display MBP, and the new Macbook. What type of work do I do with my machine? I do not do photo or video editing to start. Most of my studies involve online lectures, powerpoint, editing excel files for my research, and youtube (lets be honest here). Any suggestions Thanks for the input, much appreciated.
