Back in October 2002, I wrote a column about this subject, "Why Shout for an Australian Cab when you can SMS?."

It started this way.

Let's talk today about a technology which is available right now. And about something which fits really well with this weblog's motto: how new technologies affect our lives.

Imagine you're in Paris and that you need a taxi. You can go outside and try to find one which is available: good luck -- especially at night or when it rains. Or you can pick your phone and call a taxi company, waiting half an hour while listening to *bad* music before talking to someone. And, of course, you'll have to wait again for your taxi.

Now, imagine yourself in South Australia, where you soon will be able to use your cell phone.

Travellers will soon be able to order taxis via SMS, if a South Australian wireless communications company has its way.

ABM Industries has developed SmartMove, which uses the GPRS network and GPS system to accept bookings and direct them to the nearest taxi.
