my daily driver is an i5 PC that I bought in 2012. Haven't even thought much about it. It had 12gb, I recently upgraded it to 24gb. No plans to really upgrade, it runs linux and get's the job done. My macbook is a 2012 too. computers have gotten great enough that we can probably run these for the next 10 yrs. The only reason I'm thinking of upgrading desktop is for GPU and likewise the macbook. Outside of GPU, I'll be fine. I'm still running the numbers to decide if I might just stick to cloud workload and if I do, these will chug on along for some more years.
