I use it for more than just phone calls. Navigation, checking things ont he internet, ordering takeout, etc. But not I am sounding like a salesman.

They may make your life easier, I just have never felt it was a good idea to talk to people when "they" wanted to talk to me. Plus, I am retired. I like my quiet time and I can easily use either my laptop or desk top to find things if I need them.
Still, I can see how they would be useful to people who need to do a lot of different things in many locations. It would be essential to keep your schedule up to date and be aware of last minute changes.
