I have an aging MacBook Pro (15") which I use a great deal. At some point I know it will cease to function well, so I made the leap to the smaller 2020 MacBook Pro (13") with the M1 chip. It runs fast, stays cool, and after a month or so of pretty constant usage, has been doing beautifully. Some of the newer features like the touch screen pad have taken me some time to get used to, but I'm learning to appreciate them. A word of caution...not all apps and software are quite ready for the M1 chip / Big Sur yet. I'm still straddling the world of two MacBooks, the older one running High Sierra and the new one running Big Sur, because some of the apps don't work perfectly on the new MacBook. But all in all, it's a good transition for me.
