(www.forbes.com)
This is a most excellent place for technology news and articles.
When Sonos first came out, they had this really easy to use, standalone device. It had a track wheel like the old iPods, buttons, and a color display. That made it easy for non-tech people to browse and choose what to play. Then they decided to drop that and go the app route. It's been downhill ever since.
