Interesting NYT article about the growing use of mobile technology in shopping

The article is an interesting survey of new cellphone-based technologies that make it easy to "hyperlink" information to products while you shop.  The hyperlinking is achieved by having you use your cellphone to snap a picture of a barcode on a product.  Once the product is identified, you can read more details, watch demo videos, price-compare with other stores and online retailers, read reviews, and look at alternative products.

I'm looking forward to the real world being more easily hyperlinked.
