The Tenori-On remains one of the most eye-catching, hypnotizing ways to make music, and Yamaha has a cheaper model coming in January. Unlike the original, it can't use batteries, has plastic casing, and the LED-lights only show on one side.
But it will also cost $800 or less by the time it hits stores (the MSRP is $1000). The original (Tenori-On W) was $1200 when it arrived last year, but the official U.S. distributor has since dropped it down to $1000. You even get a free 2GB SD card.
The original Tenori-On W is also getting an OS update in January. No word yet on what that might include.
