Our laptops go where we go – to work, through rush hour in crowded trams and buses, up and down escalators, into coffee shops, to the park. And that’s where we might forget the laptop is in the bag when we drop it on the ground and lay down in the grass. In other words, our laptops need protection. From us, mostly. We’ve got a helpful collection of cases and bags that protect against all kinds of bumps and bruises.
