I see lots of different comments here about monitors. I think you're kind of missing the point.
The point of the article is that engineers value being trusted and allowed to create the work environment that bests suits them.
Whether you prefer 3 x 23" monitors or a single 30" monitor or even a 13" MacBook Air, you should be able to use the tools that make you most efficient (especially if you're being paid $120k+… what's the impact of a $1,000 27" display on the cashflow).
