Cambridge,Massachusetts,United States

Jennifer Wunder, an associate English professor at Georgia Gwinnett College in Lawrenceville, Ga., says she likes to keep her college-provided cell phone handy to send text messages and e-mails to students.

Wunder, 38, says her interaction with students is way up because she's reaching students on the same device they use.

"It's an incredible educational opportunity," she said.

On Jan. 7, she'll join about 75 fellow employees who will unplug their office phone and go wireless for good, said Lonnie Harvel, the school's chief information officer.

With the holiday season approaching, the nonprofit One Laptop Per Child is looking to use advertising and an alliance with Amazon to provide more low-cost laptops for children in developing countries.

To promote this year's version of its Give One/Get One (G1G1) program, the Cambridge, Mass.-based OLPC has arranged for donations of television time, billboards and magazine ads by such major media companies as the News Corporation, CBS and Time Warner, according to a story in Sunday's New York Times.
