Ok so I currently have a 2011 MacBook Pro, I've been thinking of updating soon and having seen Apple's event I have to say I really like the look of the new MacBook, how would this compare to my 2011 MacBook Pro? Would there be a noticeable difference in the screen (none retina vs retina) and with the SSD vs my current none SSD machine? I don't use my MacBook Pro for editing or games anymore I have a iMac for that. My current macbook is used mainly for university, writing, watching iTunes content, surfing the web, Facebook, YouTube and that's really about it. I've had my MacBook Pro since 2011 and if I purchased the new MacBook would it last as long? (4 years and counting).
