I suspect there may be a fair few people in my position who would be happy to scale down. Whether or not that is actually the case is, indeed, a question for market research.
I don't think you'd be happy scaling down. You may think you'd like it, but when you can't watch a video on your phone and laptop at the same time (and that's not even talking about anyone else using WiFi in the home), you'll quickly realize why no one uses ADSL any more.
