Whether you use Skype or FaceTime, or you do a weekly video podcast, the quality of the video camera you use is important. It also helps to have more than one camera to switch between, for variety and to make your video look more professional. Most webcams are USB-based, and I've often found that HD cams can actually "overload" the USB bus so that only one can be used at a time.
That's why the Logitech Broadcaster Wi-Fi Webcam (US$199.99) is such a pleasant surprise. By using a Wi-Fi connection to beam 720p HD video to your Mac or iOS device, it's possible to use two or more HD cameras at the same time. The Wi-Fi connectivity also makes it possible to place the camera anywhere
