And now the "Disklavier" has literally cut the cord in the latest stage of its evolution by adding Wi-Fi connectivity.
The piano can download tunes from a computer to its own hard drive or transmit files to a PC so that they can be burned to a CD. Or, as Gizmodo points out, you can program it to play itself while you're on the bench so your parents won't assume they wasted all that money on lessons.
