I rarely answer the land line at home (I get about 3 calls a year - so I'm pretty sure it's not for me), though I do answer it when we are expecting "important" calls.

I have a cell phone for work - which is nice because that means I have it for emergencies. (Why I have a cell phone at work I can't figure out, since a) when we got it we didn't have service in our building and b) I'm at a desk with landlines.)

But even though a bunch of my friends have my number - they also know that it's turned off outside of business hours under normal conditions.
