Free is the right way to do WiFi

Lately I see more articles that WiFi Internet Access should be a free service. The Billing and Customer Care systems make WiFi to expensive. So you should just add it to your existing services (food, coffee, whatever) and see it as a marketing cost.

This brings me to the question whether we should still call it a service. Something to think about: what are the boundaries of a service? [via BoingBoing]
