I really, really hate my cell phone with a passion.
I have an older phone and my cell provider has begged me to sign another 2 year contract (it expired last year in November and I am on a month to month contract). 99% of the calls I get are someone wanting something from me, work wise (unavoidable), advice, or trying to sell me something. The 1% is the good stuff like wife and family.
I can phone and do sms's from it, and that is enough.
I have a friend who last year was driving with his daughter in the passenger seat and trying to talk to her. She was ignoring him and typing away on her phone. He took it out of her hands and threw it out the window of the moving vehicle. She doesn't do that anymore....
