I have a 2021 M1 pro and see no reason to upgrade it... ever?

I do web & general java work on it and it's plenty fast even using a memory hog like IntelliJ (which is typically disk bound anyway). Claude tells me that a new macbook would feel about 1.8x faster in my CPU-bound cases, which is not common.

If memory prices returned to normal and if local inference gets over the hump, I could see upgrading for local AI agents, but I'm fine waiting for a good long while on that.

I say all this as someone who, five years ago, was a perpetual upgrader: immediately bought new product and got excited for next product. Wonder if the future will see the end of that culture in tech and, looking back, it was a little silly and wasteful anyway.

I'm also using an iPhone mini 12 and it's fine.

I too have an M1 Pro and it does everything I need to do. I bought it in 2023, so it's 'only' 3.5 years old now.

Maybe this is the tipping point where hardware companies can't rely on the upgrade cycle for sales any more. I've always upgraded at least every three years, but with the combination of high RAM prices and good enough performance from an older machine, there is no need to.
