Was End of October on NokiaUSA's website, Yes.
Was November 18th a Press Release from Nokia itself, Yes.
Was it available on November 18th, No.
NokiaUK release date was last week, now this week, but still no shipping information released.

Have you been on twitter? You might want to go look at all the #N900 tags about shipping delays.
How about Amazon being listed as a e-tailer in the Press Release by Nokia yet Dell seems to be shipping before Amazon, Amazon having no date for shipment yet because of Nokia not providing Amazon with a date. Either way Nokia is at fault for me.

Everything people are complaining about Nokia can solve. So I really don't need to provide anyone any sources as the 4000+ posts in this thread should be enough of a source.
