I wondered about that.
I can't help but think if people found it comfortable having monitors positioned anywhere other than directly in front and vertical, someone would have already positioned them at an alternate angle and position. Arranging them otherwise may even require semi-circular desks.
I'll admit I can't abide fingerprints on my screen; I'd spend more time cleaning it than using it. (Aw geez, would I have to turn the dumb thing off before cleaning to avoid the wiping being inpreted as input?) I also question the use in gaming, where your forearm may be obscuring a vital portion of the screen. That's a class of software that may require major overhauls, but I'm specualting as a non-gamer.
