I used to root for piracy only. Given how cheap the apps are, I really see no use doing it now days though. Most have demos, so I try them, and go straight into it.
I think limited feature free apps are annoying. Time based full trial would work better for me in testing if apps are right for me.
+1 what you cant pay 1.29$ i don't understand people pirating mobile apps when they can cost 1-5$, are you that poor, but you don't mind spending 500$+ on a smartphone!
