Of course a walled garden is safer than the wild west. I bought into Apple's ecosystem for my phone, because reliability and stability are very important qualities to me for that type of device. And I haven't been disappointed with my choice. Where this approach suffers is with my newly acquired iPad. The iPad is quickly becoming my laptop replacement; I do way more with it than is practical with my phone. I've started to bump my head on the roof of Apple's iOS. The limitations can be irritating. I'd be willing to sacrifice a little safety for more options. Perhaps that will come with time.
