Sonos keeps playing if your phone moves which is a pretty huge plus, especially if you know people and don't lead a life of solitude. Their hardware also has a wealth of hardware features like analog and digital inputs, zero-delay input monitoring which makes them suitable as TV or computer speakers, the ability to monitor those inputs from any zone, even if you aren't listening to them on the physically attached player, phase-locked multichannel playback, a zero-config self-extending wireless network, multiuser queue management, and twelve years of flawless software support (so far). The idea that you get the same thing from a raspberry pi, an android, and some hacks is strictly for those valuing their own time at zero.
