SnapTell

This one is for all you iPhone owners out there. Even though this doesn't include me (yet! I'm holding out for a pink one), I thought this was too cool not to share.

From Apple:

"You're at the mall and see a DVD, CD, book, or video game that looks really interesting. But, you start wondering, can I get it for a better price? And what kind of reviews did it get? Pull out your iPhone. Start up SnapTell. And take a photo of the cover. SnapTell will deliver information, reviews, pricing from other vendors, even directions to other stores. Best of all. It's free."

How does it work? It uses advanced image recognition technology developed by SnapTell to instantly match an image against millions of product images. Get the app here.

Now if only they'd develop one to help you compare prices at the grocery store.
