In this case they have some justification for the RAM at least. They use a SoC, not a more typical CPU. And the RAM is available for both graphics and system memory, so for some uses, you could do things on a higher end Mac that is not possible on a typical consumer PC.
Still sucks for people like me though. I really want to switch to a mac Mini for my NAS/home server but I can’t justify the upgrade cost to get a useful amount of RAM.
