“Pick up most books about building web sites or products for mobile and you’ll hear a common refrain extolling you to pay attention to the mobile context. Usually this means paying attention to the fact that people using mobile phones are likely to be on the go, have limited attention, and slow Internet connections. This may have been true in the past, but data suggests that this behavior is changing: 93% of smartphone owners use their smartphones while at home, 62% of people use their mobile phone while watching television, 69% use mobile while shopping, 39% of smartphone owners use their devices in the bathroom.”
