Conclusion: The new controller starts up much faster than the original, but it also consumes battery power much quicker. Sonos claims two to five days of battery life, but we got just one day’s use out of our evaluation unit before we had to put it back on its cradle for recharging. The cradle, by the way, is included in the price of the new controller (it’s a $40 option on the CR100).
Pros: Brilliant touchscreen user interface; brighter display with double the resolution of the original
Excerpt: The Sonos Digital Music System has a lot of things to like, but the thing that grabbed people at its launch in 2005 was the controller: it looked a bit like an overgrown Apple iPod , complete with touchwheel navigation and a big, beautiful screen.
