Ask HN: What will be the next wow product like the first iPhone?

Apple has lost their mojo. We need a visionary that will introduce a new product to the world that will make as big a impact as the original iPhone. What will that product be? What product would move technology 5 years into the future if it came out today?

My opinion is it would be a flexible, expandable, HD screen. Your mobile phone would still fit in your pocket, but you can easily expand it to a laptop size screen.
