I gave up my cell phone in June and let me tell you, my life is better for it. I haven't missed it, even one time, although I still may wish I had it if I'm abducted by a serial killer or escaped convict and need to call 911 from my car.
I use store phones if I need to check something, it's not a big deal. The best part is my phone never rings unexpectedly, or vibrates in my pocket, making me swerve the car into another lane. Nobody can find me. I love it.
I'm sorry to say, guys, I haven't missed the internet, either. My office is lost and cold and looking more like a basement storeroom, no life in it. The couch and the remote are happy and not so lonely, however. I have more time. It's more peaceful without it.
You should try it, really.
