while i agree that insulting people is generally not a good way to get your point across, what he's saying is that the landline is just about dead - I doubt anyone that moved out of their parent's house after around 2003 or so got one - why would you? When all the boomers (like my parents, and many other's parents) die out, the land lines will die with them.
don't get me wrong, this is not about me (or anyone else) WANTING the land line to die, and I completely understand why people keep them (everyone has your number, etc) - but for those of us that never got a chance to buy one (i grad'ed college in '05 and already had a cell when i moved to an apt), there's just no reason to ever get one.
