I wouldn’t get too hung up on the RAM. Went from an XPS with 64GB that used about 16-20GB in my day to day, still able to use the same workflows and memory is handled fine behind the scenes on my M1 Air with 16GB. Maybe get your hands on one from a friend and play around with it. Would imagine ram heavy tasks like rendering etc would choke but I just run many workflows / builds simultaneously which works fine.
16GB might be passable right now, but I am regularly using 20-25GB at a time on my work laptop, a 2019 15" MBP, occasionally bursting to ~30GB when I'm really pushing certain dev environments.
I keep my personal laptops for a long time, and I don't want to be stuck with 16GB when it's getting close to not cutting it now based on what I do. I can't imagine being stuck with 16GB in 8-10 years.
My current personal laptop, a 2015 13" MBP, has 16GB of RAM. I can't imagine NOT upgrading.
All fair points, but the deal is these M1 MacBooks make more out of the ram they have. And I can’t imagine not upgrading a laptop in 8-10 years, still have a T430S but it can’t keep up with any reasonable workflow today
