I bought the Zeppelin Air for it linking straight in to to my itunes system and control from iphone. The sound it produces is quite simply astonishing. i had been used to 'whole' sound with previous Bose systems and docks, but this is almost unbelievable.
Setting it up on the wireless network is not as simple as it could have been, especially when I then changed my router and had to go through the whole sorry process again. Tip - when its set up sit back and enjoy it, dont change your router!!
