It was fairly easy to set up, but not quite frustration-free. It wasn't able to extend the current wireless network (apparently that's only with Apple's AirPort Extreme and some other 802.11g base stations, not with our Linksys), and it took a few tries to get it to just join the LinkSys network.
But that worked at last, and I was able to set the laptop to beam music to the stereo.
Oh, it's so nifty.
With a few clicks, I can execute "play randomly from all our Austin Lounge Lizards CDs." (This is interesting because we have 9 Lizards CDs and only a 5-disc CD changer.)
Without getting up from the couch.
Lori, by the way, is delighted by a few of the MacOS visuals. She loves the Cube transition from Fast User Switching. And then I showed her the iTunes visualizer... it's no surprise that she finds it mesmerizing, because I do too, but she's been squealing with enthusiasm every time it shifts to an attractive color scheme.
