I'm keeping my maxed out Mac Mini 2018/20 at least for another 2-3 years. For my use, Logic Pro and composing/mixing, that model is still quite powerful. The only real annoyance (except for the loud fan) is the underpowered iGPU, that can mess with the audio at lower latency settings, which shows how pathetically weak the Intel iGPU in this machine really is.
It's not a deal breaker though, and I prefer that vs. struggling with all the audio software compatibility issues still going on with the M1/M2. Ideally Apple would release an updated Intel Mac Mini this year, that could carry us over for the next 2-3 years, while the remaining audio plugin issues are being fixed.
As with many others here, I cannot justify updating my Apple computer (or iPhone) as often anymore, as everything is getting more expensive now - and the price inflation on Apple's stuff is about the worst for electronics products, here in Europe. It's a shame though, because I love getting the latest and best from Apple.
