A lot of people in the residential side of things don't really understand the different speeds anyway. I was talking with a fellow telephone guy a week or two ago and it turned out he'd just had somebody come to him with exactly the same story that I'd just gone through with someone here. They were both claiming to have a DSL connection of over 50Mbps!
Of course, it turned out they were looking at their LAN speed to the router, and needed an explanation of the difference and how to access the router configuration page and line stats.
