I've been a lurker until now...
I've had my droid for about a month. The other day was bored at the bar I work at with a buddy, was looking through the marketplace and found "shopsavvy." I dled it and started scanning things around the bar including, a bottle of coors lt, the movie goonies, a plastic wrapped CD. I will say the bar I work in is only lit by colored red fluorescent bulbs and a few spotlights. I had to be in a good amount of light for these to scan, but it was obvious once one item scanned what the camera should look like for it to work. It didn't give me a price on the Coors lt, but did identify it. The plastic wrapped CD didn't scan until I unwrapped it, but when it did scan it didn't find the completely no name demo cd left behind. The Goonies scanned easily and pulled up the amazon and walmart price, walmart complete with address of the closest one.
A few days later I was at REI, found something I was interested in, but couldn't find the price. Scanned the barcode in about 2 seconds, and pulled up REI's listing for the product, price, and closest location, which happened to be the one I was standing in.
Since then I've scanned a bunch of random crap. What I've found, case pack products, like soda, if you scan the bottle or the individual product not the case or wrapping I've had much better results. I don't know why this is, but I found the case packs rarely find anything, while the actual item would scan 95% of the time.
There is one thing I could see as being a problem with this app. It takes a little getting used to where the camera needs to be, and at what angle to make sure light is able to get to the barcode when trying to scan. Once I got a few to scan it was a no brainer.
Hope that helps.
