100,000 iPhone applications, Do we need so many?

Are the AppsFire statistics only valid for apps that are used by AppFire users? It'd be useful to compare statistics for how many apps are used more than once or twice after installing too.

Apple sold 7.4 million iPhones last quarter alone. A single digit percentage of total users is still A LOT.

Do I need 100,000 apps? No. I only use a dozen non-Apple apps, but I'm willing to bet that even if you use only a dozen apps, we're not going to be using the same ones.

There's a lot of junk in the App Store that maybe no one uses, but quantity doesn't necessarily mean there isn't quality in numbers either.
