Not for everyone. I know a few people that prefer to run real hard drives in their hardware, especially when they show at vintage computer exhibitions. These people go out of their way to get old ones for spare parts and to repair what they have. Adapters are the last resort when the drives they need can only be obtained for astronomical prices or not at all.
Oh yeah, for sure, I know there are many purists who want the legit original hardware. Just that many hobbyists who just want to run their favorite old computer(s) opt for the adapter as it's a lot easier to buy a bunch of SD cards, even if the adapters can be a bit pricy.
