The design concept of a "cellphone pen" has been around before, and some products have even hit the market, but none are as slim and ingenious as this one. The design is provided by an anonymous individual. He told us that this "Design A" is still an unfinished product, and the company he works for (which remains unnamed) wants to gauge public interest in this product. Most users would connect their cellphones to Bluetooth headsets, and the two target-shaped areas at the top and bottom of the device are precisely the earpiece and receiver. So far, so good. Dear readers, what are your thoughts?
