This post comes from Tucson, AZ, where I've worked on a Windows machine for days! Nevertheless, I succeeded in connecting a Logitech (TM) QuickCam (R) communicate STX (TM) webcam to the machine, and using it for slow-scan video-augmented audio/visual chats using Skype (TM).
The communicate STX model interpolates input from native VGA sensors to generate 1.3 mega-pixel still images. It produces live video at up to 30 frames per second, includes a built-in microphone and uses RightLight (TM) technology to compensate for low-light scenes. However, it lacks the RightSound (TM) technology of high-end QuickCam models. When set atop a thin-screen monitor with speakers at the bottom, the STX occasionally creates a feedback loop, or echoes, in Skype.
