Literally. I don't use a cell phone. Promise. I keep a house phone as it keeps people from calling me every second of the day. I felt like the cell phone was just a way for people to keep tabs on me. I just get sick of the whole " Hi, how are you....by the way....where are you?" So, yea...just got sick of it.
My iPod touch has been my "phone" for years now. I use Textfree with voice as well as iMessage for free texting and calling, when I have wifi, which is nearly all the time.
I don't have to use my mobile phone but it certainly makes life easier. I do a lot of my administrating from my phone so that's a plus. I also keep tabs of the various things I have to do and collaborate on the run with my boss(es), hall council, and more.
As for the whole keeping tabs on me thing, people don't. I don't post my whereabouts or what I'm doing on social media, only close friends have my number, I'm relatively private. No less private than I'd be without the phone, just with it I'm able to be efficient.
I never had a Cell phone until about two years ago. I'm now 28yrs old so 26yrs of my life I did not have a cell phone. I now only use a cell phone and got rid of my land line as it's much cheaper this way and people can contact me anytime and anywhere if they need to. I have no problem's with it.
I also use my phone as a GPS since it has one on there for when I'm driving. It's great!
I might as well not own a cell phone, because I was satisfied with the old cell phones without the apps and most of the games. I pretty much only use it to contact my parents to pick me up or drop me off (even though I do use it, because hey, apps).
