I own the free*gimme* Nokia phone you get when you sign up with AT&T.
I LOVE mine, but not for the "wireless" conveniences. I disconnected my home phone because I am not here so much, I already have cable modem, and just don't like talking on the phone - period.
I just use the cell as my main line.
So - no long distance bills, plans, no $30+ monthly fee JUST for having it on - no telemarketers, no name in phone book, I give the # out to who needs it and that is that. Shows you the # same as caller ID when someone calls, comes with voicemail so you can screen it if you wish, I just find a lot of advantages to keeping a cell instead of a land-lined one.
I'm on one of the cheaper plans so I am limited to like 500 minutes a month, which I never go over. Also have free night and weekends, so ....
As for dead zones, I run into a lot of them out in the country, but for the most part anywhere i would have problems is covered.
I have to admit a big pet peeve of mine is seeing someone driving and talking on a cell phone. Nearly every wreck I've witnessed that could have been easily avoided involved one of those things. Ever see some teenage girl flying down the highway @ 80, smoking a cig in one hand and talking to someone on the phone in the other while trying to put on lipstick? Makes you pray your mom is driving somewhere ahead of her.
They should make a law where you have to pull over and stop to talk on your phone.
