I've met people that won't load *ANY* apps because they don't know if they are safe. I have tried a few, but am still a bit nervous about it, too. Can someone explain why developers write and maintain the free apps? ... I mean, it seems like a ton of thankless effort. So, is there some other benefit, or are they harvesting information from me, or what? I can understand the motivation to SELL an app, but the FREE apps ... why? Don't get me wrong. I'm not saying they shouldn't, but I'd like to know why they do it. And what should people watch out for when loading apps? Why do some apps need to see my location or my contacts? It has nothing to do with the app. I cancel the install when I see that, but I'm sure many people don't.
