Surprising tech that goes nowhere
Since it was introduced in March 2011 the 3DS has been one of Nintendoes best selling handheld consoles, it featured 2 screens, the top one being 3D and the bottom one being a smaller 2D screen. While the 3D screen was new to consoles handheld or otherwise, the second screen was also innovative and incredibly generous.
But what's happened since? Nothing. The idea that a second screen is useful is without doubt, so why hasn't anyone picked up the idea an run with it? Why no mobile phones with a screen on the back? Or clamshell phones with dual or triple screens? The PC space has the ability to add a second monitor, but these are usually expensive, but on a small portable device like a phone or iPad? Not so much.
Then there's the apple touch bar. This one is a revolutionary idea, a functional and programable if small screen that has a multitude of uses.
Why aren't we seeing it being sold as an optional extra to PC keyboards? Why haven't apple added it to their own keyboards for desktop users?
Again another idea wasted on one single product.
