I find being online too much really toxic. It turns me into something sub-human, disconnected from the Earth, disconnected from compassion.
So although I have a cell phone on which I can check email (I'm self-employed) I refuse to buy an iPhone, iPad, GPS, Nook, Kindle, or any more gadgetry that allows me to be disconnected from real natural life and learning...we all have different views on just what that means, so ymmv. I think people who walk around with bluetooth devices clipped on their ears (when walking down the street, grocery shopping, etc.) to be the most ludicrous of all. It's "somebody important might call me and I can't be bothered to take my phone out of my pocket when they do." My goofy husband once walked around the grocery store with a baby carrot stuck in his ear, until I saw it and laughed so hard I thought I'd choke.
This is one of two forum-type sites I visit. I check in with Facebook about once a week, if that. I blog occasionally, and I do like receiving and sending emails, but like ANM, my emails are like real letters with complete words, capitalization in the right places, and even a salutation
To me, addiction to technology, gadgets, and the immediacy of online life is something I am careful to avoid. I often "unplug" just to remember what it's like to live in the moment, talk to real people, and lay in the grass making shapes out of passing clouds.
