I have to say that most of my friends would be damn impressed if I was flipping through songs in my car by talking to it!
It's less intrusive than having a conversation on a car hands free kit, and practically everyone uses those these days (I believe they're about to become a legal requirement throughout Europe for mobile phone calls). At least an "empeg conversation" is likely to be very short!
Of course, it's not really an issue anyway, as we have no intention of replacing the other control methods. This is an additional feature which some will love and some may loath.
