Ok, I'm not talking about the business style of synergy, actually I'm talking about one of the neatest utilitiarian app's I've seen in a while. Ian Hall has this going for his work computer and the MacBook Pro he has.
Synergy is an app that lets you share 1 mouse and keyboard between multiple computers. It is like a KVM but software based and doesn't require a keystroke to do switching. Best way I can discribe it is having multiple monitor setup. The mouse just enters the other screen. It doesn't care about OS.
First thing when I get home this puppy is getting installed.
