Its an Amazon out there..well on your iphone at least

As I was browsing through amazon I found out they now have an app for the iPhone - so what? Well the amazon app not only lets you browse and buy items from your iPhone  but the feature I found interesting was the "amazon remembers" feature. This feature allows you to take a picture of an item you may see at the mall with your iPhone and send it to amazon, (I do this already to remind myself of price or color of an item) it will then get added to your "remember" list (sorta like a wish list) and in addition amazon will search for similar items for sale and notify you.  Talk about searching for the best price?
