Thanks for comments, thoughts and your own experiences.
It seems the Zeppelin Air is by far the most favoured, and almost all comments which refer to it are positive, For me I think the Zeppelin looks more pleasing on the eye, although that said it the Soundock 10 kind of has a pressence about it. After reading all the review's and comments it seems a 'love hate' thing with Bose.
I'm still no clearer on which one I should go for!
