The Japanese piano company Yamaha has been selling its disklavier player piano for decades. But, in keeping with the times, the latest model of the disklavier has an Internet connection. The New York Times calls it the first piano in the world with an Internet connection. The device still looks like a concert piano — it's big, black and shiny — and still has hammers and strings. But the Web connection allows users to subscribe to live-piano radio stations, and download songs from the Yamaha store.
