An intermediate step between Livescribe and a touchscreen, the Duo by KCI Communications lets you use a stylus on your standard desktop or laptop display. It works (on devices up to 17-inches) by using a base station to track the XY coordinates of the pen as it makes its way around the screen. If that weren't enough, the pen also features functionality similar to Livescribe -- you can keep notes on traditional paper and transfer them to your PC later. Currently, this bad boy is only available for WIndows machines, but Mac drivers are in the works. Now, we haven't had the opportunity to play with one of these things, but maybe you'll want to take the plunge? If so, hit the read link -- shipping now for $119.95. But not before you check out the commercial after the break -- it's a classic.
