Same here. My 2012 MBP has been upgraded with more RAM and a SSD and the battery is replaceable (but it's lasted better than my work 2017 model and is healthier!) but the cost of the new devices is so astronomical it'll be the last one I buy. Since I will have to invest in a new ARM device just to develop for their new platform, it's goodbye Mac and back to Linux (already got Windows as a side Dev machine).
