I also ordered the DR800S today. I'm a long time user (nearly 1,5 years) of the Iliad and like the display size and resolution.
Primarily I read technical books in PDF format on the Iliad, but it is sometimes very slow, especially if there are graphics on the page, so I hope there will be a speed improvement with the DR800S. The native support of ePub is also a plus for me.
Sure, the price point is high and not what I expected after the first announcements of $399, but I wanted a device with a resolution higher than the "standard" of 600x800, but not as big physically as the Irex Digital Reader. And the only available device at the moment, which fits that requirement, is to my knowledge the DR800S.
I'll post a little comparison between the Iliad and the DR800S after I get the unit.
What pisses me off a bit is that, despite the expensiveness, there's no leather cover included. They want further 42,- EUR for
that
