So Apple's trying to distract us from the much larger issue of Steve Jobs' health problems by making a big deal out of 500,000 applications downloaded from their so-called "app store".
It's unclear why anyone should get excited about this when faced with the obvious problem of Jobs' rapidly deteriorating health. The liars at Apple are simply trying to distract you all, sorry. After a boring Macworld that didn't introduce anything new (including a shockingly dull presentation by Phil Schiller) and pending lawsuits over the lies regarding their clearly sick CEO's health issues, they have to do something to distract the iCabal-friendly press. Their most rabid fans will eat this right up and you can expect their friends in the media, led by the usual suspects (I'm looking at you Walt Mossberg) to fall right in line.
I've got the feeling you can expect a lot more of this kind of silliness out of Cupertino for the next six months, or until a permanent replacement is named for His Holiness Mr. Jobs.
