I held on to my older 2011 MacBook Pro until i saw the specs on the latest ones, and decided to upgrade. There is a huge difference between my old one and the 2015, also considering my old Mac didn't have SSD, which makes this laptop much faster.
I was going to transfer all my data from my old Mac to this one myself, but the guys at P1 did it for me very quickly and i was back to work the same day!
