I've been playing around with various 'cheap' versions of ways to get my iTunes library playing through my stereo.
I could not justify a Sonos based on the price tag but it would be fair to say that all other versions have met with frustration with the household around ease of use. The proof being that we still have 100's of CDs near the stereo - much to my chagrin.
The four methods I have used to date have been
1. iPod in cradle - not useful for those who haven't used one before and locks your ipod in one place
2. Roku Soundbridge - good size and price, cumbersome UI
3. Squeezebox - bit big, remote better but still lacking in intuition.
4. Airport Express - easy to install - you just have to keep walking to the other room to control the music.
Options 2 & 3 also fail with playing protected tracks from iTunes, which is the stuff I have bought most recently so that is a pain.
The Sonos is the ultimate device - easy remote and amps with selectable speakers. Main issue is its price tag of close to $2k. I tried to purchase the one at the office that wasn't being used but no joy.
So the Remote application seems to be a great solution - all I need to do is get another airport express (previous was on loan) and I can control the remote speakers from the iPod Touch. I would take an old 802.11 g version if someone has one lying around (ok, I am cheap!). Probably doesn't have the killer feature of cueing up your next song, but on balance (and the fact you can use multiple Airport Express devices) then I'd go for that.
Unfortunately does not solve the iTunes server issue - papers over the cracks really as you can see all the servers but still means song replication on multiple servers which must be a relatively easy problem to solve.
Any other ways that people are using that could work better ? Especially for the non-technically oriented family members ?
