The new Yamaha Disklavier Mark IV is the first piano with an internet connection. It costs $42,000, plays virtually any song on its own and can function as a karaoke machine or an alarm clock. It also has a remote control, for some reason. That all might sound over the top, even ridiculous, but among old billionaire media moguls, this exotic combination of the ancient and the cutting edge will probably be even hotter than the iPhone. (That's a hint, Elisabeth Murdoch.) [Times]
