I can't believe I've gone this long without this. I always have at least 2 computers on my desk and since I run Apple Remote Desktop for our network I have relied on it for even my immediate needs. Just mousing over to the next screen is SO DANG ELEGANT, and easy. As a matter of fact I need to tweak a webpage quickly while also doing another task (which will ultimately reside on site). Site sits on the Mac on the corner of my desk. Task has to be done on my immediate machine. Merely mousing back and forth is seamless. Setup is perfectly intuitive. Nice.
