> On the other hand it's very common to use Wifi in public transport (at least here in London for the tube), airports, trains and hotels. Few people consider security when using these hotspots, making sure that SSL is enabled for all pages would be an improvement.

But do you use LAN services on that network? I think you will use that public hotspot to check facebook, hn, search something on google and stuff like that, not connect to some service in the local network of the hotspot.
