I really want to replace my PC with an iMac. The only thing holding me back is my wife's HP Laptop that only has VGA out. She connects it to our 24" Dell LCD when she works at home. Is there any way to get a video signal from a PC Laptop with VGA to an iMac? I see that Apple sells a displayport to VGA connector but, as I understand it, this only works for converting a displayport signal into VGA not the other way around.
