I've been using Butler for over a year now, and I am very impressed with it. This is the best piece of third-party freeware I've ever used, bar none. The interface is incredibly cohesive, intuitive, elegant, and Apple-like. Whenever I talk about Mac freeware, Butler is almost certain to be mentioned as the best of the best.
But Butler isn't just a nice collection of eye candy. MacWorld gave it the rare five-mice rating because of its perfect combination of usefulness, ease of use, and versatility. Using multiple clipboards, controlling iTunes, replaying keystrokes, searching the net, and controlling the system can all be done with Butler via keyboard shortcut, hot corners, the menu bar, or the Butler docklet.
I am using Butler on my PowerMac G5 dual 2Ghz with 10.3.9. So far, Butler has never stalled or crashed my system.
