How much is your current gen Macbook Pro 15" worth when trading into Apple or in resale? Apple is offering $750 to trade in a base mid-2015 15" 2.2Ghz 256GB SSD model MJLQ2LL/A. Backstory: I bought a brand new mid-2015 Macbook Pro 15" with an iGPU MJLQ2LL/A on eBay for $1500+tax (almost $1700 total). There are two sellers on eBay selling these machines. My current Mac is a mid-2014 MBP 13" with only 8GB of RAM and it's mostly okay with a 4K screen but the fans ramp up when doing anything intensive like using Google Street View. A 4K screen is a must for me as I need multiple windows all at once. I'm starting a Data Science Masters and I would like a new computer. I bought the 2015 model but I have not opened the package because I wonder if I would be better off taking the risk with the new 2019 model and then trading it in / selling it if any problems develop. That got me thinking about resale value and I wonder what the 2015 model will be worth 4 years from now - Apple is currently offering $750 towards a trade-in for the base model listed above (2.2Ghz, 256GB SSD). As a result, perhaps it's better to get the 2019 model... Edit: I can still return the new 2015 to the seller since I'm still within the 30-day return window.
