I work both on triple monitor and single monitor+workspace setups and still prefer the triple monitor for a single reason: you cannot put workspaces next to each other and get an overview of multiple windows at the same time..
Just saying it might work for you, but it's by no means a proper replacement for all of us

While I personally prefer a single-monitor no-workspace setup, there do exist several window managers that let you independently choose workspaces for different monitors rather than having each workspace specify a layout for all monitors. For instance, the window manager "awesome" uses tags (primarily 1-9) for windows, and lets you say "this monitor should display 1, and this one should show 2-3".
that's what I was thinking, I often throw a frame onto the left or right monitor.....having a single monitor would mean I'm adjusting positions all the time?
