Things that we called "feature" phones nowadays and iPhone 3 worked alright with all sorts of people. Maybe phone manufacturers shouldn't opt for putting so much bullshit into the screens. Reading news, video calling people, audio calling, recording voice, messaging. They all work alright with small screen estate and good UI design.

The only thing I see a possible issue is dealing with camera features. But, you know, tech companies should actually innovate stuff... I know radical.
