Actually quite useful
My husband has it on his Droid, and after watching him use it, I realized it's quite useful. We were in a store looking at a TV, but couldn't find the price. So he scanned the bar code...and there it was, the price, and all the details. I've also used it a couple times since then for the same reason. Way look around the store for the bar code scanner when you can have it right on your phone?
