Just a question for interest sake...
Why would you want analog output?
I can see this used in audio docks - but that is mainly due to the fact that Apple restricts the filesystem. It would be plain simple to mount the drive via USB and get a hold on the MP3s/AACs directly to play them back.
But apart from that pretty special use case scenario (keeping up Fairplay DRM that can only be decoded on Apple hardware) I really don't see another use case. If you have any further use for that legacy proprietary connector fell free to post it.
My TV is early 2004 and still has a USB 2.0 port and can decode a variety of digital formats. I guess this still applies to TVs...
...and on a side note. I'm on Samsung's Android flavor and just to let you know - AllShare was there way before you ever thought about AirPlay. So actually you can wirelessly stream any media from a variety of devices to new Samsung TV sets.
Do you control what TV is in your hotel room or your relatives place? I have a mac mini connected to my TV at home, that's not an issue, on the road is more of a concern.
Honestly, I wouldn't miss it much. From the start I was simply pointing out that the dock isn't just USB. It's funny seeing the different reactions to Apple removing legacy ports on the mac vs the possible removal of legacy connections on the iPhone.
