In addition to the announcement that there have been over 30 billion App Store downloads, Apple has also announced a couple of other stats during its WWDC 2012 keynote. First, there are over 650,000 apps available for download, with 225,000 of them specifically written for the iPad. Apple made sure to mention that this is compared to just a few hundred that are available for Android and other competing tablets.  Also, there are now over 400 million iTunes accounts with credit cards and one-click buying affiliated with them. Lastly, App Store sales have resulted in over $5 billion being paid out to developers. This is definitely a force to be reckoned with.
