I used them back when we played face to face. It was important to hide my notes and while I did hide all my rolls, it was to keep the players from knowing which rolls were important (I despise when a DM fudges). Since we play online, everything I would need a screen for is provided by the VTT.
My preference is for a 3 panel portrait, as I really don't like the landscape design. I haven't found the information on them to be particularly relevant since AD&D, as they seem to contain all the most common information that I've already memorized. I much prefer the ones that have information on both sides, with the player facing side the info more useful for them (such as equipment prices), since I feel that screen art is mostly a waste of space.
