Are cell phones worth it?

I have a lot of friends and family that have cell phones. Sometimes it feels like they are trying to pressure me into getting one. I suppose I am basically the last one to not have one. I feel like I have some good reasons for not getting one. I'll list them for you:

1. Cell phones are too expensive. From what I have seen, the lowest monthly bill is about $40, and that's if I don't go over on my minutes! That's just too much for me. I currently have a Vonage VoIP phone and I only pay $24.99 a month no matter how many minutes I use and no matter what time of the day it is. I can call anywhere in the Unites States and Canada without any additional charges on my bill. The only way I would ever pay more than $24.99 is if I made international calls to say, Brazil, or somewhere outside of the US and Canada.

2. Peak and off-peak times are just stupid. Why should I have to wait until 9:00 pm to make calls that don't count against my minutes? Why can't I have a cell phone account that is like my Vonage account where I don't have to worry about what time of the day it is to make calls? Give me an unlimited account for $40 a month where I don't have to think about overage charges and I will reconsider...

3. Text messaging... I don't get it. Why would you type a message to someone that takes you two minutes to type when you can just call them and say the same message in 20 seconds? Okay, text messaging does have its benefits. Like, when you are in class you can text message people without being disruptive. My real problem with text messaging is that I am charged for RECEIVING messages from people. Why should I pay 5 cents per message that my cousin keeps sending me, even though I tell her not to? Ridiculous. Yes, I know I can block her from sending me messages, but what if it turns out to be something that is actually important? Plus, I can't block every single number out there from sending me messages...

Those are my main reasons why I don't have a cell phone. Yes, I do have reasons for getting one too, but they don't outweigh my gripes with them. Here are some...

1. Emergencies. What if I get stranded in my car somewhere? What if I get kidnapped? Hasn't happened yet... If either of these scenarios did happen I probably wouldn't be in cell range anyway.

2. Finding people in crowds. Have you ever gone to a sporting event, concert, or amusement park and had a hard time finding the people you were supposed to meet there? I have, but I've always eventually ended up finding them without a cell phone. A cell phone would have made it a little more convenient, though.

3. People can conveniently get a hold of me wherever I am. Well, usually I go places so that people CAN'T get a hold of me. I like to get away from everyone sometimes...

Those are my reasons both for and against cell phones. Anyone else have any opinions to share to convince me to get one or to keep me strong in resisting and not getting one?
