With Brando's Mini Capsule Microphone, you can blissfully zone out when you are supposed to be paying attention in a meeting or class and let your trusty little iPhone do all the work. Actually, I probably wouldn't recommend that, but it does offer a nice back up system when you are in a meeting and don't want to pull out a 1980's recording device.
All you do is plug the device into the audio jack of your iPhone and for about $13 and a quick-click, voila, your iPhone is a recording device to aid in business productivity or blackmail...whatever your needs.
