LOL, whilst I won't necessarily include all Android devices in this, I'd argue that iPhones and better Android setups are likely the Most secure device that most people own.

Traditional PC security is way too complex for non-technical people to manage effectively, so the approach of walled gardens and vendor managed security is the way to go.

Not to say that a technical person can't achieve a better level of security with a PC/Mac, but for non-technical users, it's going to be mobile all the way.
