Hi all, I got my mother a webcam (the MS live 360 thing) for her iMac, which worked great until her iMac crapped out. Now she has a new mac mini, and of course, she no longer has a mic (none on mini, none on that webcam). What would you suggest? a new webcam with mic (specific model please)? or an external mic (again something specific if you can)? we are looking for simplicity, reliability, and affordability. many many thanks. my 2 year old daughter is very concerned that grandma can no longer talk.
