"Highly Addictive"5.0 starson by pbchef
Pros: Easy to set up, Great sound, highly portable (I have a Play 5). A lot of choices of things to listen to including your own computer music library. Very cool way to listen and explore new music.
Cons: PC interphase is not as slick as the IPAD's, in fact the I have seen all the interphases except for the sonos controller and the IPAD app is by far the best.
