Nice video demonstration! I would like to try that out between several of my systems, but have never known about synergy before now. I'll have to find out more about how it is set up and works, but being able to use just one mouse and keyboard for many systems would be so much more convenient.
I could fit several monitors on my large desk, but having to switch between multiple keyboards and mice would probably not fit and even if it could, would not be as convenient as that synergy demo showed. Thanks for providing that demo. Maybe someone can duplicate it in English for those of us who don't understand French?
