The aggravation of having to enter a passcode multiple times a day was not worth the aggravation relative to the I-Pads' superiority to a Fire given my present limited use of a tablet. Once a day is fine once my daughter showed me how to reset it.
Plus she told me that the autolock on smartphones can be reset to once a day when I get one after retirement. I'll just have to be careful about not using it for anything where security is an issue.
Strange...
