Livescribe 2 GB Sky Wi-Fi Smartpen
You're trying to jot down important notes while the lecturer continues talking and you inevitably forget something or scratch it down improperly. Fortunately, Livescribe makes a line of smartpens based around the premise that none of us can write very fast. Available in 2, 4, or 8 GB memory sizes, the Sky works like any ball point pen but also records audio at the same time.
While you can just play back the recording and listen to the lecture over again, what's even better is the pen can remember what you wrote down when during that recording. All you need to do is touch the tip of the pen to a certain part of your notes and it automatically plays back the audio portion recorded from that position on the paper. This recorder is also Wi-Fi enabled and automatically sends your notes and the full recording to an Evernote account if you have one set up. And don't worry if this pen runs out of ink as it comes with replaceable ink cartridges.
