In case you want to know the mechanics of how this is being done, Steve's using an iPhone 3GS running Ustream Broadcaster, connected through Wi-Fi to a Sprint MiFi. The iPhone is encased in an OWLE Bubo with a wide-angle lens, and has a SIMA LED Camcorder Light attached to it as well as a small directional mic. All of this is standing atop a Manfrotto monopod. Enjoy the video, and if you're at the store or in a line somewhere else, remember that you can watch this on the Ustream app.
One more thing -- due to the nature of this broadcast, we won't have the traditional chat this morning. Oh, and one MORE thing -- until we go live, you'll be watching Dave Caolo's previously recorded video stream from Boston.
