How do you improve the Sonos One speaker when there aren't too many qualms about the basic design? If you ask Sonos, it's all about future-proofing. The company is rolling out a Gen 2 version of the One that shares the same design, but includes Bluetooth Low Energy, a newer processor and more memory. In other words, it should perform next-generation tasks that would simply be too much for the original to handle -- not that Sonos is saying just what those additions might be.
