I have...6 or 7 Squeezes running (I've lost count) that supply the entire house with music. I like them because I supply the system behind the box. It does appear that Logitech is dropping that line of product which might seem bad but you should be able to pick them up dirt cheap. I've had one fail in 5 or 6 years so they are reliable. I've not streamed directly from an "i" device but I understand it is possible.
Might not apply but has anyone seen these? http://audioengineusa.com/Store/Audioengine-D2
