We went all cellular several years ago because our landline (Qwest) innundated us with spam calls even though we were on the do not call list. Eventually, we added the landline back, strictly for FAX and also for me to conduct telephone interviews for writing assignments (which don't work well on a cell). We make outgoing local calls on the landline but do not give the number out. There is no answering machine attached and we keep the landline set to FAX so that any spam callers get an ear full of buzzing. We are quite happy with our cell service by Verizon and would gladly use only that except for our FAX needs.
We just bought Droid smart phones. Loving being connected to the internet all the time. But, then again, I am a geek and internet addict.
All of our children use only cell phones. We figure if they can do it, so can we.
Karen, you can solve the phone to your shoulder problems on a cell by using ear plugs or purchasing a blue tooth device. It will save visits to the chiropractor from those 1-hour phone calls to your friend. :)
