The Apple TV is now in the Walnut Creek Apple Store. They get a shipment every morning and so far have run out by about noon each day.
The good news: Netflix on this thing is awesome. Great integration, you can rate, get more info - everything you can do within the iTunes store, but of course the price is only the cost of your monthly membership. Very very nice.
The bad news: I primarily use my Apple TV for music, so that was the piece I most wanted to see in store. Unfortunately, the staff said their network was locked down, so the one set of the menus that they couldn't show was the music menus. Harumph. Nonetheless, I'm planning on getting one.
