ok, i know i've heard that it can't be done, but i'm hoping that maybe now it can....i'm wondering if it is possible to use my imac as a display, hook it to a kvm switch, have a pc under my desk and run both the imac and PC off of the imac's monitor. i'm almost positive that this can't be done seeing as the imac has no input like that but i just thought i'd ask. this is one feature i would LOVE to see in future revisions of the imac and it would definitely make me ugrade
