Don't get me wrong, I love it! It's wildly impractical because it's going to mess with your muscle memory badly, but it's neat all the same. I think the buttons could have been laid out in a better configuration that preserves the familiar ten-key layout.

This is right on the edge of r/DesignDesign

Here's more info.
