Summary: Isight works right out of the box ONLY if you have Mac OS 10.3 AND ichat AV, Apple or other reviewers do not stress this enough this is a MUST. So on my OS 10.28, it does not work only the mic worked. I am glad I did not buy it last year I would have been very upset. One expensive mic right now until I get OS 10.4 installed and it picks up all sounds around it since the mic is not 'directed' forward to you, the speaker.
Summary: Needing a webcam for my Apple desktop, I looked at various models, from the cheapest to more costly. Being a Mac user I really thought the Apple iSight would be the best match, since Apple generally has excellent products. (After some difficulties with the seller - it was supposed to come with stand and attachments, plus USB/Firewire cable, which I later bought separately elsewhere), the iSight was hooked up, software and upgrade installed, and VOILA!!! Ready to go.
