Bleh. Come on, this is just apologist. So much spin here about how "it might not be production ready, so of course they're just 'testing' it internally before making it widely available".

As noted elsewhere, "it's a trivial component, almost akin to a tooltip".
And iBooks, one of the apps, was introduced in January 2010, and requires iOS 4.3 or later.
People who, with a straight face, claim that Apple has needed nearly four-and-a-half years (more, really, since there was pre-release testing), and since iOS 4.3 to make sure a "trivial component" was ready for the public are really grasping at straws.
