Why do YOU need it? No clue. But I can see people without technical know-how using these as a little home theater PC. Or really anyone wanting a smaller form factor. I’ve had friends and relatives get nucs because they want something really small form factor and don’t care about the upgradability cause they’d just buy a newer model 4-5 years down the line.
So they want to pay double the price for something with half the utility?
The customer is always right in matters of taste.
I’ve had a couple relatives/friends recognize upgradability was a higher priority a couple years later, but others are still using them or since changed to something less powerful. I think I still have a relative running one of the weird Intel nucs with AMD graphics.
