Is there nothing the iPod can’t do? The iBreath, which I’ll have you know sports the ‘made for iPod’ seal, plugs into the docking port of the iPhone or iPod for power. Just plug it in, unfold the straw, blow for 5 seconds and your BAC is displayed on the built-in LCD screen. I’d question the accuracy of such a device, but since it doubles as an FM transmitter how can you possibly go wrong (wink).
Available here for $80 and includes a car charger in the event you don’t have an iPod.
