I spent a lifetime doing physical labour and my hands are large enough that hitting more than one key is a common error on a full size keyboard. Your hands must be the same way, John. The ball of my thumb is a bit over an inch wide, and my daughter is busy twiddling her thumbs over a little virtual keyboard and says Dad, its real easy, you know.
What amazes me is watching these women with claws extending 3/4 inch past their fingertips typing on these things. Gets me some nasty looks for sure.
Privacy, well I grew up with 6 family party lines and privacy was hard to get, and people were offensive when you asked them to get off so you could call a doctor. The moment the phone rang, you could hear them pick up to listen to you but they didn't push ads at you.
Back then, it was a lack of respect that some people had for others. It's the same with phones today, except it is a corporate and political lack of respect.
