The usability of these systems suck. Any time a user has to think when the computer can think for them is a failure. Every WiFi access control system I have ever used has required me to configure the computer.
If the designers had actual brains instead of bits of liver strapped round their waist by dogbert then all that would be necessary to securely authenticate to the network is to give either the MAC address of the computer or the fingerprint of the cert. This configuration is going to cost several minutes per participant. Think of it on Enterprise scale and you have significant costs. And the coffee shop scenario is not about authentication, its really about getting acceptance of the terms of service.
