WPS available in wireless networks?

[gsDroid]

When I go to Settings > Wireless & networks > Wifi settings I see that available networks indicate 'WPS available.' Would someone please explain why I might want to use that method instead of just entering the WPA/WEP password? WPS = Wireless Provisioning Services.

WPS is more for a corporate environment. There's a good explanation here:
