It was only a matter of time when e-ink would penetrate the artistic forefront to be used as a tool in the creative process.  Makers of a keyboard called Sonder ($199) promise to deliver a fully programmable keyboard with individually lit keys that can be used for a multitude of apps, ranging from Photoshop, Logic Audio, and Illustrator.  The Sonder keyboard plans to drop sometime in 2016, and the pre-orders are currently a $100 off.  Although it is not detailed on the site, I would assume that they are tiled E-ink mini displays.  If it works, you can say goodbye to those hot key stickies.
