We're not being snotty and it's the functionality of the T60 is not up to the Ubuntu developers. It's Lenovo that made the T60 function as it does (Mute button only mutes) and that's done in the hardware mixer. However in the T61's case it's done in software and that's what Henrique meant with the "Yes, it was dumbed down." comment.
