I too would not return to a single monitor set up. My trade setup is a desktop w/2 LCD monitors, one with MT4 running, and the other for the forums and study materials...and then i will often have the laptop running news or other live feeds. Next set up will be a dual proccessor machine w/four monitors once Microsoft releases the new operating system and computers have caught up to its needs. . . and once MT4 mobile makes sense to have, i'll get a PDA to run it and watch the trades/currency away from the house.
