I was in Tesco at the weekend, browsing in their tech department as you do, and noticed two people studying the pricing label of the iPad Mini.

They just didn’t understand what WiFi and Cellular meant. As I was standing nearby, I asked if they would like me to explain which I did, and then answered a few other questions. They then called the shop assistant and bought one.

Sometimes, techies often forget that it is not always obvious to non tech minded people.
