I'd go even further to say, that we're at a point where not EVERYTHING needs to be smaller... our mobile devices are so small and difficult to hold, we're putting things on the back to make them easier to hold. They're so thin and fragile, we're putting thick cases on to protect them...

I'd love to see a production cell phone that is already thick with a relatively huge battery, more rugged case, and a slightly better protected display. I'm willing to bet there's a market for this, just based on otterbox sales, and the sales of backpack battery covers.

Similarly a home media player like the roku, shield tv or fire stick are plenty small. That has nothing to do with being able to innovate and create newer or better experiences.
