No, I'm not, we were talking about a CD player, and I assure you it *is*
the case that I *can* do that.

There may be no compelling reason to do so, at least. However, digital
gear offers benefits, and some people want them. Others, like me, live
in bad RF environments where POTS picks up too much noise unless you
very carefully select your gear and shield your cables. Further, the
digital phones support other features, such as the ability to manage
multiple calls seamlessly, present Caller-ID reliably (even while you
are on another call), etc.

I hate to tell *you*, but the LEC's and cable companies like to hand
off POTS to small businesses too.

Your argument: "This works fine for most people therefore it will
work for everyone." Is that really what you're saying?
> What's broken for a residential user?
That depends. I've got many years of experience with POTS. How about
a POTS phone that won't automatically hang up when the call is complete?
Really annoying when it's a speakerphone and you have to get up and walk
across the room to press one stupid button. (Our Cisco 79xx gear is
*stellar* both in speakerphone quality and in handling such things). How
about listening to the local radio station's broadcast on your POTS line
while making calls, because the cheap Taiwanese phone isn't sufficiently
shielded? I don't really want or need to go on; POTS *stinks* compared
to digital. I have no objection to you wanting your lines handed off as
POTS, but I'd like mine delivered digitally.

That's a matter of the consumer and their needs and wants.
