There are over 64,000 iPhone / iPod Touch applications available as of today. To buy them all, you would need a cool $149,000 USD. For your money you would own about 78% of all the apps. You would have to download the rest for free (22%). You would also own 22,000 free and paid games and if you're still bored, you'll have 6,300 books to read.

Not bad for an AppStore that just passed it's 1 Billionth download recently. Of course, even though only 22% of the apps are free, the 80/20 applies where over 80% are probably free downloads.
