I used free wifi hotspots only 2 or 3 times, and have not used it otherwise.
I get some free minutes with my Mweb subscription, i have not used it once.
I agree with some of the post above, the whole process of having to register, or go to a login page first, and having different hotspots at different placeis make it a bit of a mission to use.
The ease of use factor is what limits uptake. That and the fact hat at a restuarant etc, i may only want to quickly check mail or a website, for which the admin doesnt warrant the benefit of using the free service. For a couple megs, i might as well use my data bundle.
For me, if the network was open, and my phone/laptop could easily hop from one free hotspot to the next, that would be much better. Maybe i dont know howe to use the service properly - and thats something the networks must consider advising people about
