We have a shredder at work with a touchscreen. It is a shedder, basically just a motor and some rotating blades. But every time i use it i have to wait 30 seconds for the touchscreen to wake up. Totally useless.
The shredder needs to scan the document on its way through and send the contents back to the cloud for processing*, only then can the algorithm correctly detect the correct shredding settings.
