Windows Phone Thoughts: Science-Fiction Retailing Made Real

This is an interesting article about a "supermarket of the future" where different technologies are deployed in a test setting in order to see what works and what doesn't. The article goes into detail on which technologies they've employed, and the primary interface for store employees are Pocket PCs:

"Store employees are equipped with PDAs. The Future Store is testing Hewlett-Packard Inc.'s iPaq 5450 and 3970 models as well as Symbol Technologies Inc.'s PDT-8100. The handheld devices run Microsoft Corp.'s Windows Pocket PC operating system. Linked to the WLAN, the PDAs allow employees to check inventory or reorder goods by directly accessing Metro's merchandise management system at any time and any point in the store. The next phase of development calls for the PDAs to receive "soft phone" functionality, enabling staff to make calls in addition to sending messages or downloading information, according to Nikolatas. The service will be based on VoIP technology, as are all other hardwired and wireless in-store communication systems."
