ok guys i couldn't find a clear answer to this question. If i buy a new isight will it have a magnet in it to stick on the back of my new apple 20 inch display? Is this safe ? I will admit i dont know much about how a magnet will effect an lcd monitor. If the isight will how many versions of the isight are out there? Reason i am asking this is I was going to ask for 1 for christmas and dont want to get stuck with one that doesn't work with my monitor. Any help is appreciated thanks guys.
