Why? Because after you've had one AppleTV for a while, you're going to want a second one for the bedroom/den. I know I do. AND, I love mine so much that I've cut the cord on cable service. .
You know an AppleTV with an iPod Touch does almost all the things you listed and still comes in cheaper than Sonos. iPT is a great remote control for the aTV (and of course does a million other things too). aTV can do internet radio -- I use that all the time. You make a playlist in your iTunes of radio stations that you like and then sync the playlist to the aTV. You don't need the iTunes computer on to use the radio stations once you've synced. A poorly advertised but excellent feature of the aTV.
Lastly, you can do multiroom music for parties by adding airport expresses (also cheaper than Sonos). The aTV can be the source (no computer needed if you've synced your music to the aTV) and each aTV/airport express can be individually turned on/off and volume controlled by the iPT. Oh, and if you want to skip a receiver just hook up the express to powered speakers (like Audioengine speakers) or even better to a unit with wireless speakers (like Griffin Evolve) and then you have portable speakers, controlled via the iPT, that you can bring to any room or outside for parties without any wiring.
I already use my IPT for my aTV. Radio doesn't work very well, because of codec issues - almost all radios I want to listen to are WMA, unfortunately. All the other points I had still apply: No hard drive, NAS support, better radio support, multiroom support (e.g. play in sync), amplifier option (for use with e.g. B&W CM1s), no need for external screen for setup/troubleshooting/configuration.
As I also wrote, I have an AppleTV and love that - but that doesn't mean that Sonos don't have features and functionality that isn't in the AppleTV.
As per the thread, I hope a new version comes soon - with SDK, larger hard drive, less heat (and auto power down), 96/24, FLAC support and improved remote. I'd buy that on day 1.
Well I think is prudent to wait for the next release!
I change all my tv's to HDTV so I think that appletv with at least 720p/1080i output is worth to wait.
480p is not satisfatory for a HDTV.
I have many hd movies in harddisk that I see currently in my iMac or connect my macbook directly to the HDTV, but a apple tv would be much more less pain and enjoyble!!
