I have house phones, seven of them. They have a base unit with an answering machine, and all the phones are portable, wireless ones. I can take one out into my greenhouses and yard and that's good enough for me. I never wanted a cell phone when I was a dentist because, well, I simply did not want to be tethered to a phone 24/7. It was bad enough that I was ALWAYS on call sort of speak, and I felt (and still do) that having a cell phone would/could result in another "addiction". Oh, I could go on and on about what cell phone addiction is doing to our children (and unfortunately adults as well), but I won't.
