I expect more people than just me are interested in reducing tech turnover or using old tech in the hobbyist space, ie. not single handedly. And yeah, as the sibling says, if we're relying on proprietary drivers, we're not really FOSS- my fantasy world doesn't just apply to Apple.

Yes, it would be very hard. But today it is impossible, so very hard is hardly a complaint you can make in comparison.

Did my other two examples seem more reasonable?
