Does anyone have any experience with the JAWBONE Jambox? the smaller one? I am looking for something for my wife to listen to in the bathroom when she gets ready or takes a bath. I want her to be able to use her iPhone with it as well. I have heard the Larger Jambox and was seriously impressed. Just didn't know about the smaller one, every review is pointing to it and one other similarly priced brand. I would like something that can be powered by battery, small to fit on a little shelf hung on the wall, and can be carried around.
