Hmmm, the one I have is this (http://www.amazon.co.uk/Logitech-Pure-Fi-Express-Portable-speakers/dp/B0015S7YP0/ref=pd_sbs_ce_18). I think I might test it over the weekend and make my mind up, and while I think having a non-computer based way of charging it is a good idea I'm not sure I'll use it much I think I should at least try it out, if I still don't want it then and you do - ie the model's ok for you then that sounds grand. What do you think?
