With all the digital pens that are coming to market these days, one might ask whether the world needs yet another smart writing instrument. But unlike some of its competitors, Wow-Pen has a bit of experience on the subject.
Almost exactly a year ago, the Korean company came out with its "Traveler" version, which was really a mouse with an ergonomic design that could be handled like a pen. Now it's releasing its "Digi" model, which also reads and stores what you write through a wireless USB receiver. It can toggle back and forth from pen to mouse function "with the click of a button," according to I4U News.
Something like this isn't for everyone but, as far as multi-functional pens are concerned, it certainly has more practical uses than most.
