One of those two million is sat under my desk, collecting dust. I know a few others that are, and, I wonder what percentage of that 2 million are in the same situation? Because you need a few bits and bobs to get your pi working there is a major disincentive to complete and finish whatever that hobby project was to be. Hence the situation with my pi - the wait for bits and bobs, a small bout of illness and the initia…
But it is. My Pi's are running headless and I access them over Ethernet. They suck less power than a VM running on a more powerful hardware and that's the point.
edit: I admit that it's easier for Web dev than for HW dev. I'd use Arduino for HW hobbies before a Pi if the project can be done with both.
