Rupert Murdoch has confirmed, in a Q & A following his announcement of a New York 'metro' section for the Wall Street Journal, that an app for the iPad is under development (WSJ story here, behind the paywall). There's an iPhone app available now, and it's expected that the iPad version will expand upon it, with attention being paid to the iPad's big screen.
What's most interesting about this story is the extreme secrecy with which Apple is handing the process. it seems that WSJ developers do have access to a pre-release iPad, which Murdoch confirms is "kept under padlock and key." Not only that, but an Apple employee turns the key every night to confirm that the iPad is where it should be -- locked up tight, safe and sound. Not even preferred developers have earned Apple's full trust.
Apple paranoid? We can't imagine such a thing.
