I just got a new Imac, and wanted to find a way to keep the clutter off my desk but still have easy access to my macbook... I checked out programs like quicksynergy with no luck. then came across Teleport..

Its awesome! a must have if you use a mobile mac and a desktop.. or have multiple macs.. super easy setup (especially if you have leopard) and can save so much time, even allows you to drag files from one screen to another.
its basically like using dual monitors but not.... haha

o yeah.. its free too
