The chances of Apple releasing a touchscreen iMac any time soon are probably pretty low, but there are ways to touch-enable certain desktop Macs. Shenzhen-based TMDtouch has decided to take up the cause with Zorro Macsk ($199), a cover that turns 21.5” iMacs into touchscreen devices without any modifications; you simply slide it on, plug in the USB cable, and it’s good to go.
Rather than capacitive touch sensors like those used on iOS devices and the Magic Trackpad, Zorro Macsk uses infrared transmitters to monitor your fingers; Multi-Touch is supported. Those sensors are housed inside the frame, and there’s no screen coverage, so you’re touching right through to the glass display. Available in silver, black, green, white, pink, and blue variations, we can imagine some interesting uses for Zorro Macsk, and will be interested to see it come to the 27” iMac, as well.
