It only came at the tail end of an announcement of a new New York metro section for The Wall Street Journal, but Rupert Murdoch has finally confirmed that the paper will indeed be heading to the iPad. The really interesting bit, however, is that not only is the company now being allowed to work on an iPad, but that Murdoch says it's kept "under padlock and key," and that "the key is turned by Apple every night" -- a bit of hyperbole, maybe, but then again, maybe not. In other newspapers-going-digital news, Murdoch also said that the WSJ would be heading to half a dozen or more other devices within a year, although he didn't name any specific devices.
