I've just been away on business to Amsterdam with a group of my associates where we spent the majority of time in a single room discussing a project. Although we didn't spent a lot of time on the Internet -- in fact, we tried desperately to keep laptops closed so we could concentrate on the matter at hand.
However, checking email and calls home to the various homes via Skype required Internet access. The cost was almost prohibitive, but it was a necessary expense and so therefore unavoidable.
Why so expensive?
Internet access is cheap, especially in a large modern city like Amsterdam.
