Are you more productive with multiple monitors?
I personally, am more productive with multiple monitors, I have 3 17″ LCD displays. My roommates have three displays a piece.
Microsoft Research has been looking into this for awhile, and now a french researcher states roughly the same thing about larger monitors.
I’m not sure I would ever want to go back to a single monitor for a desktop rig again.
On my left display I have Outlook and my IM clients, my center display is for whatever I’m working on at the moment, and my right display is for my web browser and online books.
It is nice to be able to glance and see if there is an email I really need to deal with without having to change the focus of the application I’m working on.
