That said, if I assume that the company will last long enough, I think $75 USD is worth it even if I only get to use it for 4 years. Although if I end up building workflows around the ring, and then I have to get rid of it, that would be very annoying.
I don't understand this logic.
Do you not go to a restaurant because there's a chance they won't be around in 4 years when you might want to dine there again?
This thing costs $75. Over 4 years, that's $0.05 a day. Let's say you're 40 and plan to buy these until you die at 80. We'll pretend inflation doesn't exist: $750 for 40 years of use.
It feels like backward objection handling where people can't find a use case for something, but feel like they should, so invent a totally irrational objection to it.
I'll give you another example. A smart TV. A smart TV is more expensive than this ring, but yeah. So a cheap smart TV needs a soundbar for decent audio, and it needs a STB for the OS (streaming) in order to make it a dumb TV. It comes with a computer in it. A computer which you cannot upgrade. They decide to quit support whenever they want to (after 2 years you're generally hosed in EU). Planned obsolescence. We don't like that in Europe. I know, in the USA the current leadership denies climate change even exists. But here in Europe, we follow the scientific method, not BS.
