I would love to get an apple designed remote that can bundle all the things you need 5 other devices and or software to do. Currently, I have all my mp3's on my G5 in the office at home, which i use to stream to the media center airport. It then goes into a multi zone amp, so I can have music in the media center, as well as the entire house. ( the main amp sends the signal to a second amp in a cabinet tucked away, which sends stereo audio to 5 other zones in the house via a speaker selector box ). This works fine for my main goal which is to have the same music in the entire house simultaniously - for parties mainly. So I usually just set up a huge playlist for a party, and stream away, keeping my airclick remote handy if i want to skip a song.
However, it would be nice for apple to give us something that allowed for multiple base stations to stream simultaniously ( much easier a solution than buying multi zone amps and running miles of speaker cable through my attic ), select songs on the fly or change playlists as well as show status of itunes on the remote. We shall see....
on a side note, I have 2 of the Harmony 659 remotes. I have had several high end macro remotes, and this is by FAR the easiest to set up and use. Configured via setup questions on the website, then you send a small info package to the remote via a USB connection. Backlit LCD, smallish form compared to other macro remotes, and flash memory. When the batts die, you dont need to completely reprogram all of your macro keys. Just hit watch DVD, my IR lighting dims, thermostat lowers, the tv turns on, goes to the correct input, amp and dvd player turn on and each set to desired soundfields or other options and then the disc starts playing. So easy my tech challenged girlfriend mastered it in about 5 seconds!
