Ok so i currently have a 2011 Macbook Pro which i use for university work, however i have been wondering if upgrading to a retina display would be worth it? and of course the SSD speeds compared to my current 2011 model. I'm thinking about waiting until the 12" MBA is announced and maybe getting one of those, or failing that i've been thinking about the RMBP, i do need a lot of storage around 1TB because i save a lot of work and download a lot of iTunes content such as TV shows. What is your opinion on the retina MBP? is the screen much better? also is the battery life a lot better than the 2011 Macbook Pro? Is it worth an upgrade from a 2011 Macbook pro?
