I bought a Griffin iCurve for my powerbook, and a 23" Apple Cinema display for my mac mini this week. I found this great little application called synergy that allows me to control both computers with one keyboard and mouse. The mac version is a little flaky, the mouse cursor doesn't hide when leaving a display for example. But otherwise it is fantastic. I would highly recommend it to anyone who wants to control multiple computers without purchasing a KVM. The instructions for setting up synergy as a startup item are a bit vague, so if anyone has questions feel free to ask.
