I would agree with some of the other posters here - it depends on the work you do. I use two 28" monitors at home, and very rarely do they have distractions on them. A webpage I'm referencing, an IDE, another browser for testing, at least two or three terminals for various testing, editing and configuring, perhaps another tool for debugging. When I have to work on my macbook pro I find I'm much slower, because I constantly need to change between all these windows, and some can be very, very frustrating to switch between without setting up intricate keyboard commands.
