I still have my landline. Heck, I have dsl with it. I don't care for caller ID, if telemarketers call I threat them, then they leave me alone.
Plus with a g/f you tend to talk for a couple of hours a day, lol.
Also I need it for my business. I don't like cell phones. I carry a pager, and I can call back those who I choose to call back without having the line tied up and them knowing i'm on the phone

no really, if somoene is on a cell phone and you call them, you will hear a third ring in the background or a muffled beep.
I have an answering machine so I don't have to pic up the phone all the time or rush for it
