One thing, and one thing only, got Jim Stritzinger to take up running. It wasn't new running shoes or a desire to trim down or get away from the computer, he says.

It was a small sensor in his shoe that he is not even aware of anymore.

Stritzinger, 45, belongs to a growing number of fitness fanatics who rely on wireless technology to monitor workouts, offering them real-time coaching and a social network. Where pedometers once ruled exercise gadgets, these virtual workout buddies are taking off and adding more capabilities (prices range from $50 to $700).

When report cards went out for students in the Clarksville-Montgomery County school district in October, most of the 29,000-plus students did not have a printed version for their parents to sign.

A growing number of districts nationwide are making the change says Ann Flynn, director of education technology with the National School Boards Association.

The latest novel from best-selling romance author Jude Deveraux isn't exactly a book. "Promises" is a reading and viewing experience, a digital text in which videos not only complement the narrative but add to it.

"Promises" is one of four online video books being published Thursday by Simon & Schuster Inc. in collaboration with Vook, an Emeryville, Calif.-based startup that integrates text, video and social networking.
