How long do you go before replacing your MacBook?

Mine is an Apple MacBook Pro M1 2020 version, and I actually didn’t realise that it’s now getting into its 5th year! Still working though!

My very first 13-inch MacBook Pro lasted 7 years, and it’s still here, waiting to be recycled (keep forgetting to). Also had an 11-inch MacBook Air, but it got too slow at some point, so upgraded to the one I currently have and I’m trying to make it last as long as possible.

My husband bought a MacBook Air last year that he hasn’t used at all. He spends all his time working on his corporate Dell machine and wanted a ‘private laptop’ that he has little time for. Because it’s obviously a newer MacBook Air, it probably has similar (if not better specs) than my existing MacBook Pro. Will need to think long and hard, if I want to have a Pro or an Air next time round.

How do you guys decide when to replace and whether to go for the Pro or the Air?
