YES. Ordered it right after the media event. We currently have our iMac hooked up to our tv so we can access our movies and tv shows, but we have been looking at getting an Apple TV for about 6 months. Just hadn't gotten around to it, and it was a little on the $$$ side. I already re-encode or rip everything using handbrake, so it all works in iTunes.
Why I like the new one: Well we use Netflix, but don't have a box that supports it, and I still want to be able access our library on our iMac. The $99 price tag sold me instantly. We probably won't rent very often at all, but having those two main features, streaming from a computer and Netflix, I was convinced. Plus when airplay goes live it'll be sweet to stream to it from our iPhones.
That said though, I can see how someone who already has a 1st gen Apple TV wouldn't want a new one.
