Here’s a report from Mashable about this…
…to quickly quote from the article…
Android has just rocketed past a major milestone: 100,000 applications available in the Android Marketplace.
The announcement was made with just a tweet from the Android Dev Twitter account. “One hundred thousand apps in Android Market,” was all the tweet needed to say to spread the news. The search giant recentlyexpanded the Android Marketplace to 20+ countries in an effort to kick its developer ecosystem in high gear.
Now, I know Apple’s app store has nearly three times as many apps, but with Android growing as quickly as it being on such a wide variety of handsets, you have to say that any developer that is ignoring the Google offering, is simply shooting themselves in the foot and losing potential customers.
