Like something from Mission Impossible, the Livescribe Sky Smartpen comes with either a 2 or 4G memory and its very own in-built microphone and speaker for recording and playback. Through its Wi-Fi capabilities it can even send your audio notes to Evernote as well as being able to access your previously recorded ones from just about every one of your gadgets. Oh, and like all pens, it's capable of good old fashioned writing too, if you really want to get all old school on us.
