I have about 40 SmartHome-brand Insteon switches in my house. Every year one or two of them crap out and need to be replaced at $50 a pop and an hour of tinkering with wiring and controller programming.

Automation can be useful but I'm not sure if it's useful enough to justify the continuing maintenance overhead.

So the phone may have the hardware for it, but not actually be wired up. The real question is why?

Because the circuitry required to utilize the shield (ground) wire on the headset as an FM antenna increases the ground impedance and causes left-right and capture-playback crosstalk. The latter can be fixed by the phone's echo canceler, but the former cannot.

That's why FM radio is mainly confined to lower-cost phones. Premium phone buyers tend to be more particular about the headset audio quality.

Or, the sound server/mixer in the phone could switch from MP3/AAC passthrough to mix-and-reecode whenever there are multiple streams, and switch back to passthrough once the music is the only remaining sound.

Sure, that's technically feasible, but since nobody cares about mp3 passthrough anymore there's no incentive to implement it.

FLAC and OPUS are royalty-free nowadays, and OPUS is even a IETF standard. Bluetooth should consider introducing them to Bluetooth...

That would make many people very happy. No idea what BT SIG is up to these days.

Trivially possible, but it would have required a MP3 *codec* core, instead of a purely MP3 decoding hardware core as done back then, which would have risen the cost of the SoC and thus of the feature phone.

You have a funny definition of "trivial".

Correct me, if I'm wrong, but 25Mpbs figure is basically using AMP - Alternative MAC/PHY. Or in other words, using Bluetooth over a 802.11 transport (i.e.: over a Wifi transport).

Nope, you're not wrong. That's what I get for skimming the results for latest BT specs. Regular Bluetooth EDR is more like 3Mbps -- the data rate is one order of magnitude greater than hi-fi audio, not two. I stand by my assertion that faster radios aren't needed for high-quality audio.
