Bottle opener cases have been kicking around the block for ages, but the iOpener case is a lot cleverer than it looks. It actually contains an accelerometer, which detects when it's being used, and then opens a drink-tracking app.
The app, BevConX, lets you input the drink you just opened with the bottle opener, with the time and location also recorded. You even have the option of updating your Twitter or Facebook friends with the fact you just opened a cold brewski. Of course, not all your drinks consumed will come in a bottle - nor be opened by your fair hands - but for any serious drinker, that blind eye being turned by the app is probably for your own good.
