Nokia has invented a way to let you use a touchscreen on a mobile device without looking at it. It's done with this special lid that has a slot in it with slightly raised places on it that you can use as a guide. Working with the software on the screen underneath, certain spots of that slot coincide with various functions on the touchscreen, giving you eyes-free control of that user interface. Notice in the picture there's also a version of the idea with a "rotator lid," apparently with click stops to guide your fingers to certain locations on the touchscreen. These are some great ideas for those who insist on driving while dialing. [US Patent and Trademark Office, via Unwired View]

It doesn't have the same track record for improved performance as Intel. In the past it's stumbled, barely keeping pace with its larger competitor. If competition is going to be sustained - if we're going to have long term competition that drives down prices and puts faster chips in our computers, than even a minor architecture change from AMD needs to have big and speedy results. The second generation of Ryzen does.
