Hello, I am in the fortunate position of having a bit of spare cash to buy a ipod/ipad dock as our primary music source. But of all the systems i am looking at none seem to have the combination of features which I am looking for, in summary; 1. I have all my music in MP3 format 2. I either listen through my MacBook, Ipod Nano, Wifes Ipod Classic or my current device of choice is my Ipad. 3. I would like a portable device i.e. battery powered as well as mains 4. I think that wireless/Bluetooth would be useful as i am not so keen on the docks which have Ipad plugged into the front of them. My current short-list includes; 1. Bose SoundDock Portable - the problem being how do I use it with my Ipad? Is there some way of connecting a 3rd party Bluetooth dongle to it? 2. Sonos Play 5 - No battery..... Are there any devices that the Users would recommenced I audition? Thanks.
