Gets me both ways--can't read in a car, can't play most FP games (shooter or not.)

With FPS I can clearly tell which ones are going to be a problem. Anything where the whole viewport moves at all rapidly is an issue, especially if it is something other than a straight scroll. But I'm fine with pretty much anything where my cursor moves within the viewport, the viewport only scrolling when I reach the limits.
