Hewlett-Packard and Swatch Group recently forged a revolutionary technology partnership to build the world's first wristwatch that delivers on the promise of the Internet. Swatch will now be more than just a fashion statement, more than just a reliable timepiece. You put it on in the morning and go about your business with no concerns. Although initially the appliances will require a password or PIN, eventually they will use biometrics fingerprint, iris, face or voice recognition to identify the user.

BadgePAD, a smart badge that might be used in a work setting. In a hospital, for instance, doctors could pick up a BadgePAD when they arrive at work. The badge would know what's going on around the physician because Web servers would be embedded throughout the facility. In that setting, the hospital records system would recognize a doctor when she entered the patient's room and relevant charts would automatically pop up on the computer screen. If someone approached the screen who wasn't authorized to see the patient information, it would go blank.
