Congratulations, Android fans — you now have a whopping 100,000 apps to choose from in the Android Market. The 100k milestone means Google is gaining ground on Apple’s App Store, which is now approaching 300,000 apps. Of course sheer volume isn’t the whole story when it comes to mobile app markets, and many would agree that Android and iOS share roughly the same garbage-to-gold ratio when it comes to available apps. Google has yet to formally announce this milestone through standard channels, though the company has confirmed the accomplishment via its AndroidDev Twitter account.
