Look to the future because new capabilities are being added to mobile devices on a regular basis. For many people, mobile phones have replaced landlines and with good reason -- their capabilities are far superior and sometimes more reliable. [Personally, though, that annoys me. Often, talking to people on cell phones means bad connections and poor reliability. -- Ed.]

As this new technology arrives on the market, it will benefit more companies and their sales representatives and other travelers. The more you can stay in contact with your office while you're on the road, the more of an asset you are to your company -- and that always leads to solid career growth.

Heather Wardell received her first Palm handheld in 1997 (from a boss who couldn't get the hang of Graffiti) and has never looked back. She worked in banking as a systems analyst for four years, and then moved into elementary education, teaching computers at a private elementary school for four years. Heather is now a full-time writer with two main specialties: articles that explain how a particular technology works, and short stories that usually involve technology run amok.
