If the pen is mightier than the sword, then where does that leave Livescribe's new 4GB Pulse? Not only can you write and take notes with it, but you can record audio too. And with the new higher capacity model being added to the lineup, you can capture 400 hours worth of lectures, presentations, or whatever else it is you plan to record. Other notable specs include an audio jack, integrated speaker, OLED display, and a USB connector.

The multiplatform pen added Mac support last November, and courtesy of a recent software update, the Pulse now boasts support for Windows 7. In addition, Livescribe says it plans to add an app store for the Pulse sometime this year, though the company didn't say what kind of apps will be offered.

Available in black or silver, the new 4GB Pulse carries an MSRP of $200. As a result, the 2GB model has been knocked down to $170.
