My first thought was, "I thought I was the only one on the planet still using a modem."
Then the article opened, and I saw they're talking about cable modems.
But, I've wondered about this before... Will a conventional modem, with the standard telephone jack connect to a 2007 iMac? If not, what??
A serial-port modem will not. However, if you need a modem, you can buy a USB modem from Apple that will work with any current Mac.
