I've always been a Windows user, but I've recently taken up web development/coding and therefore I have been taking a look at buying a MBPro. Since I would want at least 512GB and 15 inches, the ~$2.7 - 3k plunge has left me really hesitant to pull the trigger on a brand new unit. Really all I would use the machine for would be coding in VS and general web browsing/development and primarily I would use it docked on dual monitors. There is a 2015 15 inch 512GB/16GB/2.5ghz i7/Iris Pro on Swappa for 1,150 with a battery cycle count of 259. It seems for my use case it would be safer/smarter to go the 2015 used route, but I just wanted to solicit some thoughts from actual Mac users before I make a decision.
