That said, I have to believe it's in the ballpark, as I can't see eInk releasing a shot that didn't present their product in the best possible light, so to speak. (I saw the shot taken outdoors against a grassy field as an attempt to show of what it looked like read out of doors in sunlight, to prove it could be, and to show off the color values relative to "natural" colors.)
And if it's in the ballpark, my unimpressed comments stand. This might do for some material. It won't do for me, and I frankly doubt it will look so much better in person than it does in the product shot to change that opinion.
The applicable question is how much content is out there for which color eInk would be adequate. The stuff I want to view includes things like art and photography, where it wouldn't be. RHEL 6 manuals might be an exception. I have stuff like that, but I convert it from HTML and view it on a device with an LCD screen and 16bit color.

Well, stated Dennis....those sort of needs are pretty much the same as mine. I can see the current version potentially adequate for basic graphics such as call-out boxes and, graphs, charges or to differential parts of text or equations, program code or similar from previous examples.
Most of us remember the old CGI era of graphics and while it seemed like a quantum leap for a home computer, at the same time we well knew it was not even close to what was needed in the end. Basically it was a nice way to create charts in 1-2-3 spreadsheets.
I see this color gamut as about the same level, granted more color depth but still it's far from be able to handle today's needs graphics wise. Of course on solution would be similar to how many printers handle things with 8, 10, 12 or more ink tanks to increase the ability to generate more shades of a given color.
Also as you mention pure white is a MUST to create bright realistic colors and that just has never been present in e-ink's way of doing things. I sense it's is the wall of limitation that e-ink cannot overcome until they create a totally different display tech.
For people just reading this I would offer this example. Your color printer will generate it's best colors on the whitest paper you can find. And that is because using the inks in the printer there is not only no way to create true white, there is also no white tank.
If e-ink can ever overcome this one obstacle they just might have a chance in the longer term but if not they will be relegated to the niche of reading novels and similar books.
