I like Android because the devices are so cheap... like my nice 20 dollar smart phone. (a pre-paid burner that I never registered and just use as a dirt-cheap mini tablet)
But the security is crap... Apple is far out ahead in both price and security IMO.
If you want security and can afford the $$$ then get an iPhone.
You can pick up a Windows Phone for just as cheap. Less apps, but a much faster (= better battery life) OS and none of these hideous security holes.
