I have 2 new macs, (24 and 27), only 1 of which I use at a time. It is sinking into my consciousness that ScreenRecycler is the best way to utilize both computers, and to use the 24 as the second monitor, via ScreenRecycler. This is more apt, I think, than TelePort, which works dandy. I make books and I have InDesign on the main computer; and the toolbars, Photoshop, Excel, at al, on the second monitor. I copy and paste a whole lot, and Teleport is not appropriate for that. Any downsides to ScreenRecycler? All I need is that program and a cable? Anything else? Any help appreciated.
