I had a friend who bought a new Mac every year, selling his old Mac. His calculation was that it was about the same price as keeping one Mac and upgrading every 5 years.
I'd consider leasing a Mac through this program. I priced one out, with the options I chose it's $8149, lease for $177 (6372 for 3yrs, 8496 for 4yrs).
Yes, at the end of those 3 years I don't have a mac, I have to keep paying, but I'd prefer a new Mac every 3yrs and it's just easier than trying to sell it for $1777. It doesn't seem like a bad deal to me, plenty of people lease cars. Plus, if you consider you can keep your moneny in interest earning account, then at 3% you'd end up with $2256
I'm not saying that makes it a good deal for you, but I personally like the idea of not paying out $8149 day one, especially for something I know has a shelf life. I'm on an 2021 M1 Mac. It works great. But I've also tried to run 70b LLMs and run out of memory (64g), so I think about upgrading to 128g which, being Apple, I can only do by buying a new mac.
