Others include stands or have a tripod thread that lets you mount
them on a standard tripod.
Microphone Many webcams include a built-in microphone. These can be
useful for simplicity, but you will get better audio quality from either a headset
microphone or a microphone that you can position freely.
Windows Vista or Windows XP compatibility Most webcams sold nowadays
include drivers for both Windows Vista and Windows XP, so compatibility
is seldom a concern. However, if you dig up an old webcam designed for
Windows 9x, you may have a hard time finding a driver for it. The main
thing to avoid is buying a webcam designed specifically for Mac OS X.
