I actually came across this in the wild last weekend (Phillz Coffee in Noe, SF, if anyone is interested).
On a laptop it's no different to any other landing page on a public WiFi network, except you see a Facebook branded page asking you to check-in to connect (or to skip check-in, which I did, and it connected me straight away). Putting privacy concerns aside, it was easy to use and pretty painless.
