Once you get it (...Broadband), you will never be able to go back to Dialup again.
How True!
But another reason for keeping a "dial-up" capability is to send and receive faxes.
Unless anyone knows of a way to get into the Public Service Telephone Network at sensible cost from a Broadband connection. That would allow fax sending but, to receive faxes, you need a 'phone number.
