20,000 Apps at Your Disposal

"Our friends over at Apptism, a site that tracks and rates App Store apps, have pointed out that their counter recently flipped over the big two-zero... zero zero zero. That's right, only three months after hitting the 10,000 mark (and that took only six months), the amount of apps in the store has doubled, and there's no sign the acceleration will be stopping any time soon."

Pretty impressive, doubling the inventory only three months after hitting number 10,000. And download numbers appear to be going along with it, hitting 500,000,000 mark about a month ago.  It doesn't hurt that Apple appears to make it pretty easy to write applications for the iPhone/iPod Touch, and the approval process appears to go smoothly for most of the companies.
