Back in the 80s, operating systems were a new experience and you accepted whatever they had. By the 90s however, people became accustomed to certain features. Near the top of the list for windows users was the two button mouse. Sit a person down new to mac and they freaked out for lack of a right click. Eventually, apple added the functionality, in the form of contextual menus, and USB so any PC mouse could be connected for the full right click experience. In the early 00s, the pattern repeated. Smart phone platforms were new and we accepted whatever they had. And in the near decade since, people have become accustomed to certain features. Last month I was swapping pics with another guest at a restaurant and the subject turned to our tech. And almost before anything else, he blurted out that he could never go iPhone - for lack of a back button. Then last night shopping at Target, found a clerk with a store 'PDA' for a stock check. It was an iphone in a bar code scanning special case. It had been issued the day before and he was struggling. 'No back button' he cried! This begs a few questions: 1) when will apple start offering this functionality 2) what would/should it look like, and 3) what do we tell android users in the mean time who genuinely want to or have to switch?
