I was so surprised when I opened up my gift this morning. Now I'm only missing my new TV, which should be arriving in a few days, and I'm all set! 
I got mine a few months after they had come out - someone who got one wasn't using it as much and sold it actually here on this forum.
I love mine! I use it in my bedroom and I don't have to lug DVD's upstairs anymore!
I also purpose purchase all my content on it and then it puts it all on my iTunes server (a cheap PC) so that Apple knows people are using it!
Part of my bumming around at home today since the stores are closed is ripping some of my DVD's for it...
Enjoy yours!
I think Apple is going to continue to do cool things with it - especially with the rumor that they are going to an iTunes video subscription service - what could be more perfect than using an AppleTV for it!
