I am much less tethered than most, but I don't know if I could give up what I have. My cell phone gets used maybe twice a month. I don't even turn it on anymore. I think it would be really hard for me to give up my computer, mostly because I wouldn't be able to "talk" to you guys! I also have to use it for research at grad school, since everything is available electronically. I have to say, it is a little uncomfortable to me when I have to register for classes on line, have electronic conversations on Blackboard (thankfully, none have been required in the classes I've taken so far), because I can never remember what steps I have to take to do each thing. I do like email, generally, because I don't like talking on the phone. I will call friends to make plans or if we haven't communicated for a week or so, but generally, I don't talk on the phone to just "gab." So email allows me to take care of a lot of business type transactions without having to use the phone. When I see all of these people texting, I really wonder, why do you have to talk so much? Like, how many friends do you have? I have a pretty active social life, but I just don't feel the need to be connected so much. I will never get a Blackberry or I Phone, especially since I don't even know how most of the functions on my regular cell phone work. I use a $3.00 day planner to write stuff down, but mostly I remember it all in my head.
I rarely listen to music and when I do, it's on the radio in the car or a CD. My IPod is programmed by my DH, since although I have been shown at least 3 times, I can't figure out how to download songs.
As far as cycling/running gizmos, I ditched the HR monitor about 4 years ago. As others have stated, I was focusing on it too much. I know when I am working hard or not! I do have a computer, with cadence on my road bike, but I mostly use it for keeping track of miles. My average sucks, so I don't look anymore! I got a Forerunner 101 for running, mostly because I needed to know how far I was running and I wanted to know my pace. Hey, I was pleasantly surprised when I first got it, but it's the cheapest Garmin around and it doesn't work if the g-ds aren't smiling the right way. I barely can use it.
With electronics, as with mechanics, every time is the first time for me.
