This is something that worries me. As far as I know, Apple have a good antivirus software in iPhones, I have never not felt secure using it to check my bank and order online. Would worry more about that kind of thing if I switched to Android...
In terms of phones...
Android>iPhone>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>Windows Phone
Never get a Windows Phone if you value basic features such as connecting to the internet, being able to charge your phone, and sending/receiving texts.
I never will get an Apple computer but I did have an iPhone 4, three years ago. I have an iPod and even though I constantly fight with iTunes, I like my iPod.
I like mac cause i feel like it lasts longer, thats why i buy the iphones and tablets from them, if we are talking computers then windows cause yeah i have a school mac its not mine and i dont wanna sell my soul for one.
I had all Apple products except for the TV so far and I find them easier to use than others plus I'm sold for sleek designs. My parents use Android and I can't get used to it. You do you
