So crunching #'s from E-Ink's product sheets, this is what I'm getting:
http://www.eink.com/products/matrix/High_Res.html

Mechanical / Dimensional - 9.7" Display
Pixel Count: 1200 x 825 (SVGA)
Active Area: 202.9 x 139.5 mm
226.4 mm (9.7") diagonal
Display Thickness: 1.2 mm
DPI: 150

Mechanical / Dimensional - 6" Display
Pixel Count: 800 x 600
Active Area: 122.4 x 90.6 mm
152.3 mm (6") diagonal
Display Thickness: 1.2 mm
DPI: 166

Code:

Here it is compared a little easier:
width	height	s ratio	diag	wres	hres	r ratio	dpi
3.57	4.82	1.35	6.00	600	800	1.33	166
5.49	7.99	1.45	9.69	825	1200	1.45	150

I think it's kinda interesting they're switching the "standard" computer resolution ratios of 1.33 to something more in line of a 3/2 ratio.

I wonder how that will impact picture viewing and the like, ending up with white bars on the edges. Free flowing text obviously doesn't care, but for static-format PDF's, 11"/8.5" is 1.29, which is more inline with the K2's res.

Also, I dunno how much the 16dpi difference will impact the screen, but if some had problems with the fuzzies on the K2 pre-fonthack, it might be even worse on the 150dpi screen.
