hi, my question has been asked many times but most of them are pretty old now. I used my MBP early 2011 13 inche for a while now and looking to upgrade. Then I see my friends MBP 17 it's pretty awesome. I know the Ratina MacBook are great too. So as for 2016, do you guys think it will worth getting MBP late 2011 17 inche? Thank you!
