It's not a question of what's the most common. It ought to be a question of what capabilities do you think of when you think of "a computer". Most people do not think of their phone as "a computer", even though us tech heads all know that it is literally just that. We need to follow the lead of most people here, and recognize that the phone is a deliberately limited device and its capabilities do not define what "a computer" is or should be or could be.
