I've been running a Win PC from my Mac for more than a couple of years using Remote Desktop. Effectively I just switch to the Windows computer as if it were an application. I just came across this appealing alternative
http://synergy-foss.org/
I'd still be using the same mouse/keyboard; I'd just have to set up a second monitor. The key appeal is that it allows one to copy/paste across the two platforms. It would also allow me to do things on my Win box that aren't accessible via RDC.
Anyone here use Synergy?
