I can't help but feel like Valve has somewhat dropped the ball by not releasing it yet, at least for other handheld manufacturers to use in their own devices. As it is, the Steam Deck is the only handheld PC that I know of that uses linux, and all the companies jumping on the bandwagon with competition are all using windows. It feels to me like Valve's attempt at making linux the de facto standard handheld OS for gaming devices has slipped away by now, which is really unfortunate.
Of course, the Steam Deck is still the most popular handheld gaming PC (in large part I'm sure due to low cost and the convenience of SteamOS) so it's not like it has been a failure at getting more gamers on linux, but I'd guess that if they released SteamOS 3 alongside the Steam Deck it would have made a much bigger dent in the market.
I'm polyamorous myself, with a girlfriend of about 18 months and another of nearly a year. Both my relationships are stable and very fulfilling, and also relaxed and laid-back. It takes more communication to have it work but for me I can't even imagine living any other way, polyamory feels right for me and me and my partners are happier than we've ever been.
Granted, my relationships aren't a case of opening an existing partnership, but rather I talked about the fact that I'm polyamorous to each partner very early on before we even considered a relationship. Most drama I've seen in polyamory comes from one partner in a monogamous pair wanting "more" and so the decision is pretty one sided, and neither is willing to really put in the work and communication that healthy polyamory requires. Every polyamorous person I know that started their relationships as polyamorous is healthy and happy in their partnerships.
