I think this is great, wonderful to see WiFi becoming more prevalent. Seems like a good fit for airports and large venues.
Also came across a new Facebook enabled WiFi for businesses called Wavespot which is making a splash too. Customers connect to free wifi and can "like" a business on Facebook instantly. I think they do a bunch more things like giving digital coupons through wifi etc. It seems like a good way for small business to provide free wifi.
All in all great to know that ill be able to use free wifi in a lot more places in the future.
