No I think the all time classic is Krugman saying the internet will be no more influential than the fax machine.

It's funny, but in a different genre, because we should expect Krugman to be clueless, whereas in theory people on geeky tech websites would be better.

Similar to the HN'er who dismissed dropbox as an ftp clone (iirc), some geeks live so close to the tech that they can see how a product is simply an iteration on what they understand/own etc. and miss the marvel of the entire package as a mass market product.
