I have downloaded (and paid for) a lot of $2.00 programs that are just amazing. It’s not that you couldn’t make these on the PC, it’s just that people would scream that it should be free. And as a developer, I can tell you, I won’t spend time making stuff "for free" when I could be spending that time with my kids unless it’s a labor of love. As a result, a lot of cool little programs are being made because developers can actually get paid for making cool stuff.
