I just got the JBL Creature speakers for my iBook for Christmas, and they kick all kinds of ass. Previously I was routing my sound through my Boze system, but that involved a lot of wires all over the place and was generally a pain in the ass. The Creature speakers actually sound a bit better than my Boze ones, believe it or not. Plus, they're tiny (decent-sized subwoolfer hides under the desk) and look cool as hell. They also have a volume control on the right speaker, which is kind of a cool feature.
