I've got a mini hooked up to my LCD, but I'm still thinking of getting the AppleTV. I like they way you can sync content with your iTunes Library. Its like having a ipod with proper outputs right next to your TV. I've never really picked up the PVR/Tivo thing, if I miss it live the first time, I generally don't find time to watch it later. And if I want to catch up on the Whole series, I'll probably just get it on DVD/ or iTunes Store (in about 10 years

).
I get the feeling that AppleTV is going to be a serious contender for the mini. I think that lots of people got the mini as a second mac (with first time switchers going for the macbook or iMac instead).
