I had to upgrade from an M1 Pro with 16 GB to an M4 Pro with 24 GB last year because one of my work projects at the time needed multiple docker instances, and 16 GB wasn't enough. This year 24 GB isn't enough for a few AI models, but there's no budget for an upgrade...

My home "servers" don't do much but 8 GB or 16 GB of RAM is enough them, for now (Linux).
