8GB of "unified" memory. That means it's also shared by the GPU. I realize these things aren't meant to be gaming rigs, or CAD workstations, but I do agree that this isn't very forward thinking.
It's mostly for people who need to edit some documents, a few photos here and there and other things like that. 8GB of RAM is going to be enough for the average user.
it is quite forward thinking, but for Apple, they are thinking you will need to upgrade.
I use a MacBook Air with 8 GB of memory and it's fine. If I've got a browser and VSCode and Blender and PrusaSlicer and Claude and XCode all open it gets a little slow, but Mac is very good at memory management these days.
Someone using just a browser and Word would have absolutely no problem.
