Mirasol, besides shifting color with angle, is an All or Nothing technology. Photos will be worthless on a Mirasol display. Rather like a white light hologram without the 3D effect. However, diagrams and text should be very nice. Since E-Ink can't do color yet, I think it may be a good trade off.
I have been hoping to see a product which uses Mirasol. It's a good move for Taiwanese manufacturer. Taiwan indeed has been trying so many different products these days. What's up with American's corporation?
