What do you need ? - Two computers !
If you own two computers with separate screens you can use ScreenRecycler. Even your laptop can be used as second screen for your main machine.
There no such thing as enough screen real estate !
You like working with multiple documents and multiple applications? You hate when windows are being hidden behind your current application ? Screenrecycler is the right thing for you !
Use your old iMac as second screen for your new iMac like on the picture above. Use your notebook as additional screen when you place it beside your desktop Mac.
