We're going to file this under "Why weren't we notified sooner," but this might be the coolest thing we've seen this holiday season. Imagine, if you will, a device you can plug into your iPhone or iPod that contains both an FM transmitter and a breathalyzer. No, this miracle machine isn't the product of some Utopian fantasy - it's available now, and you might not be able to get it in time for Christmas, but we bet if you order it now you'll be able to see delivery before New Year's Eve, which is when you really need it. Just imagine, if you blow in the breathalyzer and find you're a little too tipsy to drive, you can listen to your iPod through the radio transmitter until the cab comes to pick you up. Brilliant!
