I suppose it was only a matter of time before a company decided to use the same E-Ink technology found in the Amazon Kindle and Sony Reader on a watch. Now that someone has, the result is interesting but slightly underwhelming. At the push of a button, users can change the watch face design —unfortunately, these changes are confined to a black and white face and various digital and analog configurations. It is a decent first try, but the technology probably won't be truly useful in this capacity until color E-ink displays become available. Available for $250.
