The Pen Recorder is a clever concept, very clever: a pen that remembers what you write and then send it via Bluetooth to any compatible device with this standard.
Probably it will be much appreciated by those who prefer to write your notes in ink and then store them into soft medium. With a decent gratitude program would be even possible to quickly convert them into digital text.
While this is just a sample, there are already similar pens, made from English Live scribe, a company that specializes in these "smart pen". The Recorder, if it were produced, would be the first to use the Bluetooth standard by far the most convenient way to transfer data between the devices and modern gadgets. Unfortunately, there are not enough details about price, storage capacity and battery.
