When you consider all the different applications for iPad — from functioning as hotel check-in machines to swipe-brochures-in-store to managing passenger manifests on airplanes — there’s a whole load of possibilities crying out for a smaller device with the same general functions. Something that ISN’T an iPhone. The iPad is a bit rubbish on the train. It’s good. But it’s bad too. You know what I mean if you regularly travel on a crowded commuter train. First, you need to use it sitting down. Standing up just doesn’t work. Second, everyone knows your business. It’s too visible. It’s too easy for folk to see your emails or the latest episode of Homeland playing on the device. It’s just too big. The screen is just too bright and easy to see!”
