Hi guys, new to the forum. After not having a Mac for years I decided to pull the trigger on a open box mid 2015 15" MBP. I got if from Best Buy for $1350+tax. This was a return with 3 battery cycles (mint). Here are the specs:MacBook® Pro - 15.4" Display - Intel Core i7 - 16GB Memory - 256GB Flash Storage. Should I keep this or go for the touch bar 13" with 512GB SSD for $1550+tax? I kind of feel I bought old technology instead of going with the lasted model. Please let me know your thoughts . Thank you!
