So though I'm sick of the sound of myself talking about Apple this and Apple that, here's another observation, courtesy of my iPhone.
Like the click wheel on the original iPods, the navigation system of the iPhone can't be much of a mystery to figure out and replicate.
I suspect it's not a mater of creative ability as it is one of restraint. What to edit.
More buttons equal more options. Surely that's a good thing, so goes the thinking.
