A phone the size of a Pen

This really surprised me, this pen is a cell phone, it is a concept but like some concept cars, this one may get to the market.

As you can see it even has a micro-sd slot, the numbers are along the pen, and there is also a LCD display.

Hope to have one in the future, I think it will use bluetooth earphone as I just can't imagine where the mic and speaker is.
