Mobility trumps mobile. The difference between mobility and mobile is like the difference between hardware and software. Mobile is linked to devices — it is always one thing, wherever it is. But mobility changes with context: cultures incorporate mobile technologies differently. For example, in Africa, SMS technology helps farmers pay bills electronically. In America, it helps teenagers keep up with their friends — an average of 60 times a day. Mobile itself is the nuts, bolts, and infrastructure, while mobility is the context which determines if it all works together or doesn’t.
