I didn't get a cell until about 2 years ago, if that's any indication how resistant I was to them. I was the last person to get one, out of pretty much everyone I knew. 
That said, blaming cell phones for people acting like assholes is giving the assholes a pass. The phone didn't turn them into one.
There are a lot of assholes on the Internet, but do we blame the Internet for making people into assholes? Of course not. No one seriously doubts the utility of the Internet, either.
Considering how many kids get started on after school activities so young, yeah, I can see 6-year-olds having cell phones. Hell, it might even help cut down on kidnappings, if a potential 'napper knows every damn kid has a cell and he might not be able to figure out where it is quickly enough to get rid of it and make a clean getaway.
There are absolutely rude people with cell phones, but they are rude regardless. The phone just makes it more evident. It's an additional opportunity to look like an asshole.
I have actually noticed the anti-cell phone attitude is most prevalent in what I'd call "geek" or "nerd" communities, TrekBBS being a prime example, but I've seen it in other sci-fi forums, comic book forums, etc. Basically, "people like us" aren't so big on vocal communication, so we don't really see the need to be available by phone 24/7. I certainly don't like talking on the phone very much. I'd prefer to deal in person or in text (email, IM, forum, etc.)
But our attitude is relatively rare. Most people love their cell phones and consider them essential communication tools. They love talking and texting. They love being able to reach their friends, family, and kids anytime, anywhere. I think it's just a difficult mindset for a lot of us to relate to.
