That's like 300 $1.99 apps. I call BS. Serious BS. One, that you could even find that many decent apps to pirate and two, that you can even use that many in one lifetime.
Every one of my friends JB and none us us 'pirate' apps, so there's my test sample.
I suspect there's a few app whore kids out there who horde apps just because they can, but I think the vast majority of JBs do so for usability.
Serious BS? Give me your email and I will give you a screenshot of all of my bills. I have bought almost every EA sports game, every gameloft game (both around 7 dollars EACH), a 70 dollar NBA primetime app, and a ton other apps that cost way more than 1.99...
