This is one of the coolest toys I've played with in years. LiveScribe's smartpens have the ability to instantly digitize anything you write in a notebook and send it to a tablet or PC as a handwritten note. But here's the cool part: they can also record the sound you were hearing when you wrote those notes, timecoded to each penstroke, so, for example, you can tap on a lecture note and hear exactly what the professor was saying when you were writing it. The latest LiveScribe pen, the Sky Wifi, has built-in wireless connectivity that quickly syncs your notes, audio and all, with the ubiquitous Evernote application so you can read and play them back on your PC, tablet or smartphone. It's a fascinating device that revolutionizes the taking, usage and sharing of handwritten notes. We spent ten days with a LiveScribe Sky 4 GB.
