I totally agree with Trip and Affineur.
The Beosound5 is very enjoyable experience. I would be very interested in it if it offered me a more complete solution (better integration with both my audio and video libraries)
The Ipad with its present capacities cannot be more than a '2-way user interface' , just like the Beosound5 is just an interface for the beomaster.
It will need a backend (mac or pc), just like the beomaster, to do most of the work sending the requested content to your stereo or tv.
Does not take the fact away that the Ipad (if a proper B&O app would be developed) would be an interesting replacement (or extra) to the Beosound.
The Ipad can never be a true stand-alone, stream your library, kind of product. It was never designed to be that.
Scrolling through a big library of CD covers is very taxing on both the serving and receiving side and can hardly be done well over wifi.
To be practical way and in order to secure fluid motion the cd covers should be stored on the IPad, with the audio or video files remaining on the server and be fed to your stereo or tv from there.
The apple TV's work very well as secondary stations ( extra bedroom tv, kitchen, bathroom, etc...) for audio and video.
However, if you live in a wifi-rich area (Like me living downtown Montreal) it's going to cause problems. Alot of my video library has been ripped full Dvd quality or higher making the heavy use of my wifi system and therefore more prone to hick-ups and at the same time hogging the bandwidth for other users on my home network.
Hardwiring them with ethernet solved all problems.
