I have used all three. The tablets were fun, but useless. You need a keyboard. Computer in the room seems best, hard wired, real keyboard and mouse, big screen the patient can see across the room....
I keep coming back to the laptop and that is all I use in the room. I can set it down, or out of the room during a procedure to minimize it's function as a fomite, and I can close a chart and cue up the next patient as I walk to the next room. For me laptops are the only way to go in the room.
