I have come to believe that the M2 Mac Mini is a con and this is what we have come to expect from Apple. If you want the coolness of Apple products, then you have to pay the Apple Tax. The M2 Mac Mini is successful because Apple does a really good job of hyping its products.
I want a faster computer than what I have now, and the M2 is most definitely faster, but the base model has four times less memory and storage. Upgrading is cost-prohibitive because of what Apple charges for those upgrades, which I think is an insult. Once you buy it, you have a computer that is not upgradeable, won't run my Windows games, and could die in five years due to SSD failure that can't be repaired.
I recently saw a gaming PC on sale for $700. Not only did it have a faster processor, more storage, and 32 gigs of RAM, but those components can be replaced if they fail. Any decent PC could last up to 10 years.
There are mini PCs that can give the Mac Mini a run for its money. I'm holding out for the AMD 7940hs, which should be at least as powerful if not more so.
There are use cases, like content creation or app development, where the M2 processor with a memory upgrade might make sense.
