Yeah, and what besides watching rented movies, and okay this flickr thing, can't you do with an AppleTV and a PC or Mac now? I mean, I know the interface may get a lot spiffier, and purchasing music/movies from the sofa and listening/watching right away without buying on a computer and then syncing will be nice. But you can pretty much do everything now, save watch rentals and the flickr thing, and the latter is kind of just candy, really.
I've had my ATV since the month they were released and I still can't figure out why so many people think they are so lacking even as they were first released. I have a Blu-ray player, so stepped-on downloadable HD content doesn't much impress me, as what I've seen via other HD downloads really looks no better than standard up-converted DVDs and little better than standard iTunes movies that my HDTV upscales with its own video processing unit. Yeah, 5.1 discrete channel digital audio support for movies will be nice, I'll give you that -- but you know most Apple TV owners are using composite audio connections, so that won't matter; they'll have to go optical or use a *real* HDMI A/V receiver -- about $1,000 for openers; the $500 models are just HDMI pass-through; they're HDMI *switches*, they don't strip and process the digital audio.
Anyway, I look forward to the update. But I've had no ATV qualms at all. It's just like any other home media-sharing device, except not so freaking complicated and it doesn't tend to stop working or "forget" its source for no reason.
