Am averaging 4-5 years with MacBook Pros though I made an exception and got an M1 MacBook Air when that came out. Have an array of MacMinis still in use dating back to 2012. Debating whether or not to upgrade the sole Windows laptop I have (2017 Thinkpad X1). Most of the programming I do is run on servers, I rarely compile on my systems except for personal use toys.
