If you have an iPhone I highly recommend you get the Amazon app. Along with a fast and easy to use search feature, Amazon have included an amazing service called Amazon Remembers. Say while over at your friends place or while out shopping you found something you’re interested in, maybe its a CD, or a TV or as in my case a book, all you need to do is snap a picture of the item with the iPhone and the Amazon app uploads it online where a community of people research your photo and try to find the same product on Amazon.com. I just tried it now with a book I was interested and by the time I got home I had already received an email with a link to the product on Amazon.
Update: Just for the fun of it I took a picture of my dog eating his bone with the app and it got sent to Amazon. A few minutes later I got an email back pointing me towards a dog bone on Amazon! Amazing stuff, they’ve got a great sense of humor!!
