Uhmm... I've put there the iliad, but the other "devices" that I use (or have used) to read aren't there:
onHandPC: I started out reading PG books in the onHandPC computer watch -- yes, I know that 102x64 pixels resolution is a bit low, but you always have your watch on you wrist, so it wins on availability; also it has backlighting (electroluminiscent background) and the batteries last a reasonable 3 weeks (always on mode) or 1 month and a half (auto blank display mode).
Newton 2100: This one was a failure for me; the resolution and the contrast was somewhat off, so I only read some Sherlock Holmes in it. And yes, I bought it (ebay) intending to have a larger-than-the-zaurus device for reading books.
Sharp Zaurus (SL5500 and SL6000): the battery is terrible, but the screen is very good; in fact the 4" screen at 480x640 of the SL6000 is superb. Also the suspend mode works like a charm so in 3 secs you have the device up wherever you left it. But I use it for reading comics, not books. Panning is fast so as long as a single picture fits on the screen it's very convenient.
And for reading books the Iliad fulfill it's role perfectly (hope the community manage to speed up the boot time, though).
So that is it for me
