Shopping aids: Stores are starting to use wireless Pocket PC to find more info about items in brick'n'mortar retail stores… the link above is for a story on how SmartWorld's iShop lets you type a book's ISBN number into a Flash-enabled PocketPC to connect with Amazon's database, mail wishlists, etc. Meanwhile, Virgin Megastore lets an HP iPaq swipe the bar code on CDs to pull a sample of the music through the store's wireless, using the MusiKube implementation. (See details.) Virgin also uses in-store kiosks, but the handheld tool lets each shopper customize the info they pull. I hope to take a walk-through of the San Francisco store within the next week.
