Android's app trajectory is insane: December saw 4,000 new apps. Last month saw 8,000. This month? On track for more. In a year, the App Market will approach infinity, and our universe will collapse into a sizeless point.
For reference, it's Apple's App Store is on a similar tear, adding nearly 85,000 apps to its ranks since the beginning of the year, when it had just passed 100k. But at this scale, comparing raw numbers doesn't tell us much—the fact here is that Android and iPhone OS are the only two OSes with the meteoric growth in app development commensurate with the widespread demand and appreciation for smartphone apps. In other words, they're the only platforms that get it, for now.
