That's a good point. Apple's design philosophy does treat apps special making all apps appear the same on many different devices.

However, I am simply suggesting Apple innovate on what they started. Instead of just re-inventing the same device every year.

Like you mentioned tapping to open 'view' mode to zoom in. I've given further thought how it would work. Like placing a finger along the edge of the screen then pinch zooming with your other hand. Or using a new creative gesture. By holding your thumb at one point on the screen and using your index finger like your pinching a knob, moving your index finger on an arc, from left to right to zoom in, and right to left to zoom out.

Which reminds me of something I heard years ago. The future of hardware is software. It's only limited by our imaginations. I just hope eventually enough people will see this and agree, and come up with better ideas.
