Well it depends whether active usage is a vector in how secure a device is. If security is exposure to risk / frequency of use, you are correct, same with exposure to risk / percent of global ownership (66% smart phone, 50% personal computer), but if we’re talking about any given device with an even chance it’s a pc or smartphone, I’m willing to bet (although I don’t have proof) that any given smartphone is slightly more secure.
