In Toronto, the city has wired the downtown core for WiFi. Elsewhere I can connect at cafe's and often in residential areas just pirate other people's internet access.

I'm bringing my Palm E2 on the North Sea Route, should I bother buying the WiFi card for it?

I imagine that I might travel great distances without any access. If that is true, can I access the internet from libraries or internet cafes or other places along the way?

I guess my question is; how connected is Netherlands, Belgium and France?
