I do, I just like to know that what I'm getting is worth the money before I drop $10 on it. For cheap apps I take the risk but I'm not about to drop $10 on something I might delete 5 minutes later because it's crap.
The end of the story is that when you run a pirated app this is the risk you take.....that's why when the devs do something it takes them a bit longer so they can try and ensure all bugs are worked out for the most part
