So, I used one of these machines at our local Noodles & Co. restaurant. It's super-elegant looking, and clever in its screen interface. But there's a fatal design flaw in the dispenser unit.
The ice dispenser is behind the beverage dispenser. As you reach back to fill your cup with ice, the last couple of drips from the last beverage dispensed will drip on your sleeve. Wouldn't that have been uncovered in user testing?
