According to a friend of a friend over at Cnet, one of the most annoying sacrifices you'll have to make is dealing with the spring clips for the speaker wire, though we personally don't see it as much of a problem if the sound is as good as they make it out to be.
If you're looking for some geeky audiophile speaker talk on the sound quality, you can check out their write-up on the speakers over here.
