I wonder if using a standard desk, you could actually see a 30" screen on both sides inside your normal vision without moving it back further.
I mean, 30" is pretty huge for a monitor. I think it would be difficult to use, myself, but that is, of course, just me.We have a 32" LCD tv in our living room which I tried using it as a monitor and it was just too big for my tastes.
Personally, I'd prefer have a multi monitor setuup that one huge. My ideal setup would be a 22" or so in the middle with two 19"s on both sides.
Oh, and a ceiling mounted projector for watching movies.
