Watch TV in your bathroom, access your audio and video collection from anywhere in the house, control your big screen TV and route video to it from your desktop or the Internet. Take a dozen movies and your entire music collection with you on a trip. Strap the gizmo to the back of your car headrest and entertain the kids. Grab e-mail from a passing WiFi hotspot. Surf the web. Play video games. It will still cost too much, but a million early adopters won’t care.
