I’ve had an iPhone for about 16 months now, and I’m pretty happy with every aspect of it that has nothing to do with the wireless carrier. However, some minor complaints are inevitable even in such a well-designed device. Consider, for example, the user interface displayed upon receiving a call. When the phone is asleep, the incoming-call UI looks like this:
To answer the call, you drag the green box from the left side of the phone to the right, just as you would do ordinarily to activate the phone’s screen. However, if your phone is awake — maybe you’re using it when someone called, or you recently put it in your pocket without explicitly putting it to sleep — the interface is different:
Now, years of computer use have conditioned most people to expect the affirmative option on the right in graphical interfaces. But even a few days of iPhone use are sufficient to condition one to drag from left-to-right in order to wake the phone or answer a call. I wonder how often one has send one’s wife straight to voicemail before one develops the necessary reflexes for the more-complex behavior demanded by this pair of interfaces.
