That's what I went for I bought a new pair of ELAC UB5's for £300ish on sale, and an Alexa Echo thing as I have a Prime subscription for the deliveries. I can use them on my TV which I cannot the HomePod (unless you want to use Apple's terrible TV box... which doesn't have TV on it!) and I can use them with my Windows PC, oh and I can use them without latency, which bluetooth doesn't have... but for some reason Airplay does. Oh yeah and I've got RCA, Optical, Bluetooth, ethernet, Wifi and 3.5mm options. Not to mention the sound is way better than the HomePod, especially at the bargain I got them at.
So again why go HomePod?
I have an iPhone, I have a Mac, they both work with any device, they have ports for USB or Bluetooth or Wifi. Imagine if Apple said "sorry but you have to use our standard" and the phone didn't work with 4G, or the Mac needed an Apple Router to work with Wifi...
That is the HomePod, it is useless, I stand by that statement. And when Apple drop support for it, you have no legacy ports to still use it!
