Yeah, we had two of these replace the old school style drink stations at the hospital I work at. They had to bring back one of the old machines because the new machines were causing so much congestion in the cafeteria. Pretty sure the hardware in these predate blackberrys, they take forever to recognize any input from the screen.
Plus if you are just trying to get water, it gets slightly contaminated from whatever beverage the last person got. Especially if it's blue powerade for some reason.
