I was reading this overview of smart phone web browsers, and came across this interesting sentence about the iPhone's Safari browser:
The iPhone browser interface is a success not because it's intuitive, but because the interface is discoverable at a level almost below conscious thought.
This didn't make much sense to me, so I looked up intuitive in the OS X dictionary, and found this definition:
using or based on what one feels to be true even without conscious reasoning; instinctive
So we have "...because the interface is discoverable at a level almost below conscious thought" and "...feels to be true even without conscious reasoning." Now I'm no rocket scientist, but it sure seems like intuitive is, in fact, the right word to describe the iPhone's Safari browser interface.
