Newbie Mac tip: Apple Pro Speakers only work with the newer G4 iMac and the Power Mac G4 equipped with a "minijack." Powerbooks do not have minijacks and cannot use these speakers. The "minijack" provides both stereo audio and power to the speakers, eliminating the need for an external power supply or additional connection to a power outlet. Guess who learned this the hard way. :(

In their stead, JBL Creature 2.1 speakers are in my future. I've heard good things, and they're less than $100.
