With the growing popularity of smart phones like the iPhone and Google’s Android, as well as new players on the market like Palm’s Pre, the idea of having an always-connected general computational device is finally being realized. Today’s smart phones are not only used for making calls, taking pictures, and listening to music; now people are using their phones to do business, build presentations, make quick edits to important files, and even surf the web.

In a few weeks, the Facebook application platform will mark its second anniversary. While it garnered lots of press coverage in the months after it launched, the arrival of the iTunes app store shifted attention away from Facebook's vibrant ecosystem.

It hasn't been a good year for Apple's iPhone App Store. Child welfare advocates threw a fit over the notorious Baby Shaker application. App Store developers started to complain about slow payment of royalties from Apple. The ubiquity of iPhone flatulence applications became a running joke. And now comes word that popular industial rockers Nine Inch Nails have had their iPhone app turned down, because of naughty language. Which all leads to the question: Why is Apple in the business of selling iPhone applications anyway? One possible answer is that Apple needs to gate-keep iPhone applications because otherwise they could screw up their deal with AT&T.; ... read more

Thousands of sellers created the 40,000 apps that have appeared in the U.S. iTunes app store. Measured in terms of apps per seller, developer and vendor engagement has gotten stronger over time.
