At Read Write Web, Brian S. Hall writes about how “mobile is taking over the world,” as he puts it:

Figures published earlier this year from the UN’s International Telecommunication Union (ITU), for example, reveal the amazing spread of mobile connectivity. According to the ITU’s “facts and figures” publication, mobile penetration rates are now about equal to the global population – including an 89% penetration rate in “developing countries,” which currently have the highest mobile growth rates.

In other words, nearly everyone on the planet has a mobile phone — or will have one soon enough.
