E-Books Interrupt Themselves

In The NY Times Media and Advertising Section:   I have pondered this recently as I have started to use e-Books more often.  My smartphone and pad readers interrupt me with the gentle ping of an incoming message.   So I stop and check the interruption without having to put the reader device down.  Of course they do that even if I am reading a paper book.  All of modern  modern life has become fragmented.
