Not really a fair comparison in that the original Macintosh was competing against systems that were in the same ballpark of pricing. There weren't equivalently specced machines that were 1/7th the price.
The Vision Pro had more than double that number in the first 10 days of preordering. Estimates are Apple expects to produce ~500k units, I don't know if they'll really sell that many though, the popularity is waning quite quickly.
That's my thought as well. The price is very fair considering all the tech in it, and historically we paid a lot more for less. My crappy 1997 Fujitsu laptop was $3k in today's dollars.
