Alright, so this isn't that exciting. The unofficial app count has been above 100,000 for a while. That was only the count of total apps submitted to the store, though. Today, Apple has approved their 100,000th app and sent out yet another press release to celebrate. We're all very impressed Apple, but no one likes a braggart.
The App Store is a qualified phenomenon. No one else in the business comes close to the breadth of selection iPhone/iPod touch users have, thanks to the App Store. With phones like the Droid starting to close in on the iPhone in terms of raw power and interface design, the iPhone's app selection remains a major buying point that nothing else can match. Yet.
