Well, if you want to use touch on your iMac, I guess there is now a way to do so. Troll Touch has created a user installable touchscreen option for both 20” and 24” aluminum iMacs. The price for touch isn’t cheap as the 20” kit will cost you $699 and the 24” kit $899. The kit comes with drivers and calibration software, but I don’t see any mention of a cleaning cloth.
