iPhone/iPod touch only: Amazon released a new mobile application for the iPhone and iPod touch today, ensuring that you can now get your online shopping fix no matter where you are. Not only does the Amazon app provide an excellent interface to search, buy, or add items to your wishlists, but if you're an iPhone user, the application's Amazon Remembers feature identifies any product you take a picture of—sort of like previously mentioned SnapTell. When you snap a pic, the app uploads the picture to Amazon, which looks for a match among its products. If it finds one (it can take anywhere between a couple minutes and 24 hours), it'll send you an email and update the Amazon Remembers tab. So far it's worked like a charm with all of the products I tested. I expected that my iPhone book might throw it for a loop, considering it has a picture of an iPhone on it, but even it was correctly identified within a few minutes.
If you ignore exchange-rate-related-stress and give it a go, let's hear how it works out for you in the comments.
