Seeing that one of the bar exam preparation providers uses iPads in its training (also and this), I was reminded of the possible utility of the tablet for learning. Except I don't know how to use the device for anything besides e-mail, Sudoku, and reading books. My knowledge gap is large, very large.
What to do? My first answers to closing a knowledge gap are to talk with an expert or, more frequently, find a book. Not knowing an expert, I went on a book search. Google up!
After a search, I ordered this book and will write more later about what I learn.
