Rumor Correction -- Oops - Pythaeus wrote to tell us that Apple's forthcoming active-matrix color LCD PowerBook will be called the 180c and will sport a 640 by 480 screen, as opposed to the 640 by 400 LCD screens we are used to on the PowerBooks. Why do I suspect that the 180c will sell as fast as Apple can make them despite a ludicrous price? The PowerBooks strike me the best answer to the "PC's are cheaper" argument. When it comes right down to it, the more-capable and thus more-expensive PowerBooks have consistently outsold the cheaper PowerBooks, excepting the fire sale PowerBook 100s, of course.
Smarter Parental Controls
If you've been using the parental controls options in Mac OS X to lock your child out of using a particular computer late at night, but would like to employ a more clever technique to limit Internet access, turn to MAC address filtering on an Apple base station.
To do this, launch AirPort Utility, select your base station, and click Manual Setup. In the Access Control view, choose Time Access to turn on MAC filtering. You'll need to enter the MAC address of the particular computer, which (in 10.5 Leopard and 10.6 Snow Leopard) you can find in the Network System Preferences pane: click AirPort in the adapter list, and click Advanced. The AirPort ID is the MAC address.
