We're also a cheap society. Money rules all. Its why so many people switch to VoIP even knowing the quality is in most cases worse than POTs. People will deal with some small issues like lower call quality and possible interruptions if it saves them some money.

If you tell someone they can have it in 3 minutes instead of 30 of course they'll be interested... and then tell them they're going to pay an extra $50 and they'll find something else to do for that other 27 minutes.
