I think at the $200 price point, it’s a good buy. Anything more and you’ve paid too much. The latest Homepod update seems to have improved HomePod connectivity, though I haven’t used it enough to really say for sure. But if the connection issues have been fixed, then I’d rate it as subjectively equal overall to a Sonos One, with personal taste being the differentiator. I do think that the HomePod has the capability of producing better sound, but since it lacks tone adjustment, it might not fit your taste or work with the room it’s in. Unfortunately, there‘s no way of knowing how any of these speakers sound until you buy one, which is why I think it’s ridiculous that Apple doesn’t at least have basic tone controls for the HomePod. Also if your WiFi isn’t strong, you might prefer a speaker with ethernet capability.
I wouldn’t worry about whether apple continues to develop it or not. At the end of the day, it’s an airport speaker, just like any other, so there’s little risk of it becoming obsolete anytime soon. The only risk of buying one now is really the opposite - if Apple are going to continue with the line, then they’ll likely have an upgrade as soon as they’re able to clear out inventory of the initial batch, so you might find yourself with an old generation model sooner than you want.
