For ebook devotees, reading is a whole new experience
David J. Loehr, a playwright who lives in southern Indiana, was taking his car to the dealership when a story on the radio caught his attention. A short science piece about "an obscure subject" gave him an idea for a new play. ,

He started his research for the play right there, while his car was being serviced.
"I can have all that research on a single tablet instead of carrying around 40 books," Loehr said.
