When I see that it works with my best, old-school speakers, I wonder if it has red and black posts for me to crimp my speaker wire to. But of course I know better and know that it will just provide line out audio. When they say "old school" they mean it has an RCA out jack, and when they say "speakers" they mean boombox, receiver, or modern powered speakers (the sort which often have an iphone connector on top to plug your phone into).
We as audiophiles know that the language used in the copy is imprecise and implies the wrong thing (hopefully we're also smart enough to know what it's actually implying). I suspect the average human would not be as confused.

They tried that and no one wanted it: https://en.wikipedia.org/wiki/Nexus_QAnd the product I'm thinking of isn't that far-fetched and drives a pair of Bose 301s fine.

It's crazy that regular speakers are becoming so rare.
Still, I have been wanting something like the Chromecast Audio for a while and already ordered one. Might even order more depending on how well it works. My reasoning is that I've considered setting up some basic "whole home audio" system but stuff like Sonos is expensive whereas powered computer speakers and older boom boxes/shelf systems with an aux-in are a dime a dozen. I've got a set or two collecting dust in a closet right now and you can even find powered computer speakers at Goodwill for $5 if you want to go cheap.
Either way, it's great for rooms where you might not need anything fancy but still would like to have streaming radio or listen to a music app. Just plug in old PC speakers, connect $35 dongle, and you've extended your music to that room.
Not audiophile grade or as classy as some $500+ Sonos system but I don't really need all that just to have music coming out of the spare bedroom or the bathroom or the basement (or all of them) while we're having people over or I'm cleaning the house. My current setup is either cast to living room and crank the volume, play on PC in basement and crank the volume, or dock phone into some crappy little speaker thing in the kitchen. I like the idea of just using my phone and then picking what rooms it will play in.
