Do I NEED a touchscreen computer for my scanner?

We are finally making our way into the digital world (yes, I know it's way overdue but it's been a journey as the young doc to get the older doc to put down the impression material). We decided to go with a Shining3D elf scanner, but did not want the shining3D cart - it just didn't fit well with our ops. I have gotten the specs from the rep on what we need for a computer, but not sure whether getting a touchscreen laptop would be beneficial, or just using traditional mouse/track pad would be fine. The Shining3D cart is touchscreen, which is why I ask. My biggest concern would be longevity of the screen as it wouldn't be designed to hold up to dental disinfection products as the Shining3D screen is. Do I need a touchscreen or am I asking for issues by getting a touchscreen?
