I unfortunately have no immediate need for this, and there are other things (many other things) on the priority list anyway, but hey, it is cool.
Enjoy your iTunes music library in virtually any room of your house. Share a single broadband Internet connection and USB printer without inconvenient and obtrusive cables. Create an instant wireless network on the go. Extend the range of your current wireless network. How many devices do you need to do all this? Just one.Oh, by the way, did I mention here that my mom did go ahead and get a 12" Powerbook fully loaded? Boy am I jealous! Powerbook is way down on the list to spend money on at the moment too. Maybe by the end of the year or early next year.
