Argh, no, no, no, no. Bad.

An AppsFire user spends $80 on apps.

An iPhone user does NOT spend $80 on apps. How much do they spend? I'd love to know, but even with zero background in stats I know it doesn't make sense to assume AppsFire users are representative.

This is just as bad as that "iPhone app economy is worth $2.3 billion" article. Apple just celebrated 1.5 billion downloads a couple months back - including FREE apps - I'm expected to believe the AVERAGE app cost per download is greater than $0.99, counting free apps?

Now it's $3.3 billion?
