Usingthisfeature, shoppers in a store can snap a picture of a product with their mobile phones, and the photo is automatically uploaded to Amazon.com, which then searches for a similar product.
The demo we saw showed reasonable performance here, but we still have a difficult time finding a usage scenario that involves us usingthis particular feature (especially when it's ever-present in a wide variety of phones and tablets now).
We'd be interested to see how this might scale down onto something with a little less display going on, but the Note II's ample square-inchage certainly makes this a feature worth using.
