OK, not supporting the older AppleTV simply sucks.
So, to use any albums from iPhoto 11 (and presumably later) with an AppleTV, I have to throw out the perfectly good one that I have (that has storage!) and get a new streaming thing?
That's simply unacceptable.
I don't know why everyone has their panties up in a bunch. My AppleTV 1 is working just fine with iPhoto '11.
