Tux Machines (TM)-specific
After years of having an audio-only computer, I finally succumbed and bought a USB webcam, so that I can do video calling through Skype.
First, because I'm frugal, I looked on-line to see what low-cost cameras were available at my local retail chains. The Logitech C210 seemed to be the least expensive and most available.
Next, because I use Linux, I did a web search for "Linux Logitech C210". I was hoping to find a web page where someone reported that the C210 worked well with Linux. Alas, I found no such page -- which doesn't mean the C210 is incompatible, but merely that no one has reported their success/failure yet. And I don't want to be the one exploring new territory here.
