I still like the peace of mind the landline has in an emergency if something happens to me with just minisnick around if he can just simply dial 911 without being able to fully tell them what is wrong they will still be able to find me.
I guess i speak from experience. when I was probably 5 yrs old, my mom slipped and went tumbling down the stairs while she was going down with a laundry basket in hand. It took some doing, since the phone was wall mounted, but I managed to get the phone and call 911. Then got the address book and called a friends mom. She had dislocated her shoulder in the fall and couldn't get up because the basket had sort of pinned her in the 3'x3' area at the bottom of the steps.
