Mine arrived. It sounds great, clearly better than the Bose Sounddock or the Apple Hi-Fi. The bass is very good; very clear and non-boomy, and fairly deep for a small unit but not as deep as a full-size stereo of course. The overall sound quality is very good, but not quite as good as a pair of excellent bookshelf speakers.
The main issue is that it has little stereo separation. It's actually mono up until something like 500 Hz and it doesn't do any fake stereo widening. I haven't quite decided whether I'm going to keep it; I think it will come down to whether I can sell my Apple iPod Hi-fi for a good price.
