I think mine are correctly aligned. Light is polarized when it reflects off certain flat surfaces such as water and asphalt. When I test my glasses, it kills those reflections best when my head is level.
I agree that E-Ink has some disadvantages. It will absolutely need an external light for night use. However, the Kindles (which use E-Ink) I have looked at seem to be able to update their screens reasonably quickly. Deciding if it is quick enough does need to be tested. However, when I look at the K3 and KX3 displays, the only thing that might need speed is the s-meter. They don't have spectrum displays, and the other items can probably be handled by a peak-holding the display. A quick glance at the Wikipedia article <http://en.wikipedia.org/wiki/Electronic_paper> indicates that these displays should be able to be made for selective update, or even for application specific configurations like the displays of the K3, KX3, FTM-10, and Icom 706 to name just a few. Whether they can be manufactured economically in the small quantities required by these applications I don't know. The upside of the technology is an absolutely beautiful display, much like type on paper. It doesn't fade out in sunlight and has a wide angle of visibility. Since my FTM-10 is in a Miata, it is really hard to read the screen in strong sunlight, even without the polaroid problem. (And yes, the brightness is turned up to max.)

Cheers - Bill, AE6JV Tilting my head in all cases changes the contrast of the screen, from zero up to near max.
