"If Tiger Woods had this Japanese feature in his phone, he wouldn't have gotten in trouble."

Thanks to reader John for the WSJ's Daisuke Wakabayashi report on Fujitsu's privacy phone, a.k.a. the "infidelity phone" because customers appreciate the features allowing them to better control information.

Prompting this assessment from a university professor:

"If Tiger Woods had this Japanese feature in his phone, he wouldn't have gotten in trouble," said Mr. Natsuno, now a professor at Keio University's Graduate School of Media and Governance.

Speaking of Tiger, he updated ESPN.com's Bob Harig via email on the state of his game heading into his 2013 debut next week. Tiger talks about his break, practice and swing work.

Regarding his schedule and way of life these days...

"I do focus on the majors because it's the four most important weeks, but there's also plenty to be excited about this year," Woods said. "It's the start of a new season, there's a lot I want to accomplish and build on and I'm opening 2013 at a tournament I like. It's pretty easy to balance everything out."
