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.

Many employees -- frustrated that their companies are unwilling to pay for the laptops, cell phones and other electronic devices that they want on the road -- are spending their own money to get them.

Nearly 40 percent of professionals recently surveyed by researcher In-Stat paid for a laptop that they regularly carried. Cell phone users often picked up their bill. And company-provided personal digital assistants (PDAs), cameras and Global Positioning Systems (GPS) are relatively rare, says the survey, released today.

Intel Corp.'s push to create and boost new categories of small, cheap Internet-connected devices is taking the world's largest chip maker in some unusual directions.

It's investing in wireless networks, or even buying them outright. It's relying on software that isn't from Microsoft. And it's looking at making processors cheaper and smaller rather than faster and faster.

To Chief Executive Paul Otellini, it's all part of bringing the Internet to new places and people, and computer makers are responding.
