I just read the Lifehacker article on Synergy and decided to give it a try with my laptop and desktop. Five minutes later, including downloading time, I’m writing this.
It’s so dead simple.
Synergy is a virtual kvm. It links your keyboard and mouse from one pc to any other pc you want to use it on. So instead of having my desktop keyboard and mouse and then my laptop keyboard and mouse, I have one. And this makes it easy to switch between projects. If you’ve got two computers you use near each other, I highly recommend combining them with Synergy.
