I find it fascinating that in all walks of life people use language same way. They rarely say exactly what they mean clearly and concisely. This is everyone's fault including my own because I'm occasionally as guilty as next person for not saying what I mean, but we let it happen firstly because we know and understand what people are saying when they speak to us; secondly because we've got lazy.

Language has always been constantly changing and developing because that's what language does; so who knows what extra fun you will be able to have with it in say five or ten years. In meantime, try and bear one thing in mind - next time you order a taxi, ask about availability of one - and not its external measurements.

Many carriers already have GPS cell phones available. You can buy basic model for emergency tracking or you can pay for technology that turns cell phone into a sophisticated mapping, PDA system. Problems are still an issue with advanced features. The more you use advanced features, greater drain on battery. Increasing battery size also increases cell phone size and that is a problem for most consumers who want ever smaller, lighter devices to carry around. At this time Japan seems to have edge on developing high-end miniature GPS cell phone.

Sacrificing privacy for safety is issue and I suspect that it would only take one positive outcome in an emergency situation to make decision for you.

As systems become more and more refined camera and PDA capabilities are being included into phone itself. Developments in GPS cell phone technology are continuing. If programmers can solve issues of privacy then potential for GPS cell phones is incredible. It will no longer be an issue of "Can you hear me now?" Rather question will be, "Can you find me now?"
