I had only a cell phone for my first two years after moving here in Vancouver, but I got frustrated with it. I find it uncomfortable for longer conversations, and the connection was not as top notch as I would have wanted. So we got a Vonage phone now, which is pretty cheap. (We have built-in high speed internet in our building.) It also wouldn't work in the event of a power down, though.

I very seldom pick up the phone. I can remain seated with not a twitch in my body as it rings... I've been raised on email, to which I can reply when I want. I feel the same about the phone.
