Is "I don't find this article interesting" a good reason to flag? If it got to the front page, people must have found it interesting. It seems like flagging would mean "this article does not belong on HN". I think the announcement of new phones and tablets in new form factors with new apps and an upcoming software update from Nokia would be relevant, moreso than a slightly thinner iPad with the same internals and software as the already released iPhone 5s, which will undoubtedly be filling the front page later today.
