With respect, I think we're overthinking this with the conspiracy theories,Agree. Wake up people this is how media works (ref politics)
Monday's article at the Wall Street Journal, which provided confirmation of an Apple tablet device, had all the earmarks of a controlled leak. Here's how Apple does it.
Often Apple has a need to let information out, unofficially. The company has been doing that for years, and it helps preserve Apple's consistent, official reputation for never talking about unreleased products. I know, because when I was a Senior Marketing Manager at Apple, I was instructed to do some controlled leaks.

I'm sure we'll see this guy extolling the virtues of the Mac Pro in a video on release date.
I bet he didn't even think about the non-disclosure when he took that picture and posted it.
Apple reads these forums---they won't be happy about it.
As an aside, it looks ugly as sin.
