I got mine the last time around, and, just after typing "woot.com" today, I tried again to find out how to put it in a power-saving sleep mode. From what I can tell, the only "sleep mode" you get drains the batteries in a few hours; hardly what you want from any computing device, let alone a reader. This makes it nearly useless unless you plan on using (and charging) it all the time, since start-up takes far too long.
The e-Ink screen is needlessly limited, e.g., no web browsing there, and it always puts the same start-up page on when it's off rather than leaving on the content you actually want. This and a few other quirks that prevent it from being too great, even for a specialized device.
Also, it didn't work out of the box; I needed a fair bit of Googling / trial-and-error to get it to work. Oh, and my screen flickered, but a reset seemed to do the trick there. Still, if their company's website had disappeared, I would've been stuck with a brick, which means you'd better hope they keep the site open out of the kindness of their out-of-business hearts.
