I have to have dual monitors and 7 works great with them. One of the cool featurs of 7 is to be able to put up two reading panes side by side. If you have not seen this it is done by opeing say 2 Word docs. Pull one left and one to the right. They will each fill 1/2 the screen side by side. When I do it with dual monitors - let's just say it does not give the expected results. Love 7!
