Funny, but I used horizontal workspaces with high-contrast stylus driven reflective display/interfaces for decades. When I was a kid, those were called "desks" with "paper."
Working like that for a long time sucks, but so does an "ergonomically correct" PC workstation. Also strange is that my girlfriend's RSI (non-carpal tunnel) is more aggravated by the PC workstation than it is by writing with pen and paper on a horizontal desk.
Workspace "up?" From what I remember of using a typewriter, I was still looking downwards at the "display." All of the people I see in co-working spaces and the like on laptops, even the 17" ones are mostly still looking downwards. Maybe they aren't looking so far downwards as the desktop, though my impression is that people still look downwards a lot at their keyboards.
I don't think that we're so vulnerable to looking downwards as people seem to say. So long as we have someplace we can rest our arms, I don't think we've exhausted the possible good workstation/display configurations.
