I have done it for a while because of the size of some of the projects, its just so much easier to do it this way. Recently upgraded the mac to (2) 23" displays because of the amount of fleet trailers we have been doing. Nice feature it has is that you can have the 2 monitors working standalone 1 for each of the computers, or both working off the same computer for one giant screen. Comes in handy a lot when you have 2 projects goin at the same time and you have to keep waiting for one to load or save.
