So you are not concerned that perhaps a year later, you may need more RAM?
Perhaps do what you mentioned or just buy the cheapest model whenever a new purchase is needed? Since the cheapest model is so cheap, there is no need of worrying about making a wrong decision?
I believe the right approach completely depends on a person’s needs, preferences, and budget, so there’s no single correct way to go about it. Anyone giving you advice will inevitably consider things from their own perspective as well, not just yours—because only you can fully think from your own viewpoint.
However, I can share how I do things. I always buy the cheapest basic model and use it for as long as possible, then upgrade to a newer model. This works for me because my usage is relatively light, so I don’t need to worry too much about things like RAM or the processor. I’d rather upgrade more frequently to a completely new model because technology evolves quickly anyway, and I usually get more new features than just more memory or a better processor.
For reference, here’s my Mac history:
• MacBook Air 13” basic model (2014–2019)
• MacBook Pro 13” basic model (2019–2024)
• MacBook Air 15” M2 basic model (2024–)
For example, I purposely bought the M2 version even though the M3 had already been released because I got it brand new for €500 less. For my needs, there’s absolutely no noticeable difference between the M2 and M3. I also went with 8 GB of memory, and it’s been more than enough for me. I’ve never faced any issues because of it. My next Mac will likely be a basic model from around 2028-2029 (unless my usage needs change significantly).
But as I said, this works for me and my light usage. It might not work if you need a device for more demanding tasks. To each their own!
