That's kind of a problem, too.
A top-spec M2 Pro Mini on CPU and RAM (12-core CPU, 19-core GPU, 32GB unified RAM) is $1,999.
A bottom-spec M1 Max Mac Studio (10-core CPU, 24-core GPU, 32GB unified RAM) is $1,999.
Since the low-end Studio has 10Gb Ethernet and four Thunderbolt ports at the same price, and neither has upgradable RAM, there's no reason to buy the high-end Mini.
