I was wondering about touch screens for older iMac G4s. I don't know if anyone has ever done this but I'd like to put one of the older iMac G4s in the kitchen and would love for it to have a touchscreen. I've heard of people using the Wacom tablets behind the LCD screens in iBooks/Macbooks to make them tablet PCs. Would this idea work in the iMac? I can't find anything on google, at least on the first 4 pages .
