My Fujitsu tablet has a matte finish touch screen
My fingerprints don't show up as much on this type of screen. Keeping a glossy screen clean would not be difficult though. I don't worry about fingerprints on my smartphone so why would I worry about it on a monitor. I'll just wipe it every once in a while like I do for my smartphone. I wear glasses so I always have a small lens cloth in my pocket to clean the glasses and the smartphone. I take good care of my stuff.
Hal - I too would worry about people spilling coffee and food crumbs on a horizontal surface. You have probably seen some disgustingly dirty keyboards and monitors as I have. I keep Cyber Clean putty, a can of compressed gas, and screen wipes nearby. I wouldn't recommend a horizontal screen set up but I suggested that Slayer might.
Slayer - When I am at my desk, I dock my Fujitsu Convertible Tablet to a full size monitor and use the Fujitsu screen for the Metro-style start screen and the full size monitor for desktop programs. I could spin the monitor around so that it is parallel to the desk but I don't find that position very comfortable. I usually keep the tablet's touch screen at a 60 to 70 degree angle while it is in the dock.
