I'm probably mostly in the latter camp, but still appreciate efforts like this. It's not a rational thing, but more about "reliving the past" but with more skills/money/available software. Like classic cars or whatever, where you know you could have a better overall experience with a newer car, but you want to tinker on the old one (where maybe you now got the upgrade model you yearned for back in the day).
It looks to be based on AROS - the open source re-implimentation of Amiga OS, which apparently can run either on bare metal or hosted on different OSs.
