I just received my i.Sound box yesterday and LOVE it! It is a little heavy with 12(!) C batteries in it but still nice to have it conveinent to carry. It does sync the iPod when you plug in the USB to USB cord. I also use it as a speaker system for my computer when I want to play the iTunes radio (it comes with the cord too). The AM/FM radio is nice too, however the reception, even with the antenna doesn't see to pick up except the very strong local stations. I'm looking forward to using it during my tennis clinics. Will let you know how it does outside and projects sound at a distance....
