Tab Times, a new digital magazine all about tablets, delivered as a free iPad app

Just as there sprang up magazines about personal computing when the PC was launched 20 years ago, a new online business magazine entirely devoted to tablets has been launched in New York called TabTimes, delivered as a free iPad application.

"The iPad has already changed the lives of tens of millions of people," said a release. "TabTimes for iPad will report on the front lines of this revolution with a business perspective. It will focus on how tablets are used for business, work and productivity, with a mix of news, features, reviews, interviews and how-to articles."

The magazine is updated throughout the day, with a main feature published every weekday evening at 8 p.m. EST and early in the morning on weekends.

The app is available at the App Store under the business category.
