This makes a lot of sense because...
1) Apple's customer base are the more well off people, willing to pay higher price for brand name. They are more likely to buy than your average joe
2) To pirate on Apple devices you have to CRACK the device, I am not sure if this is the same case on Android.
3) Android is based on Linux. This tells me that more of its source code is open and free. Also it tells me that the "hacking" community or people who would like to tinker with their devices flourish a lot more over there.
To be honest I like free stuff too , but as I grow older I realize that its the wrong thing to do , and some one out there has spent time and money and makes a living off these apps we use and he wants to get paid back. Also if we want more good apps like the ones we got for free , we should pay for them to encourage developers to do more.
If they don't get a return on their previous apps created, they'll just stop all together.
ps. Installing pirated software has its huge advantage, you get to check the software out before paying for it. This helped me decide on many purchases , sometimes not even the demo will cut it off. The way I see it, even if you use the pirated app for a very long time, you can always go back and pay the developer...if it was worthwhile.
