Amazon.com has launched an applet for Iphone (and Ipod) that I find very smart and useful. In addition to the regular features you also find on Amazon’s webpage, this applet also utilizes the camera on Iphone.
If you see a book in a store or at an exhibition, or somewhere else, and you want to remember that book, perhaps buy it later, then take a picture of it: The applet sends the picture immediately to Amazon.com, and if the picture has a satisfying quality, Amazon finds the book, and returns all the relevant information about it to you, including the possibility to buy it online.
Very smart. Even if you go to the webside, you will see the books you took pictures of listed at the top of your page.
In this way, you don’t have to write down authors and titles anymore; just take a picture of it with your Iphone!
