An excellent question from Bob today. There's a lot of talk about screen size. As we all should know by now, bigger is not necessarily better. In other words, it's not what you've got but how well you use it. With that in mind, what is the screen size on your smartphone and can you type with the same hand that holds the phone? And to round out the question, how big is your hand? To measure your hand, measure across the hand from between the thumb and forefinger to just below the pinky. Also measure the length from the tip of the longest finger to the start of your wrist, approximately where it bends.
