Actually the ectaco jetbook, a cheap ebook reader I got over a year ago as superb PDF support. It automatically zooms in past margins, loads all graphics and text, turns pages quickly, even on monster sized textbook PDF files. This cheap piece of hardware handles PDFs better than my (albeit cheap) android tablet. If only they had a version with a decent screen size, it would be the killer device for textbook reading.
Thanks for the tip, but the jetBook seems to use a TFT screen: "jetBook uses a huge, state-of-the-art 5-inch VGA reflective monochrome TFT screen" (http://www.jetbook.net/specifications). No word about resolution but I'm skeptical that it could compare in any way to e-ink, especially the new Pearl panels.
Oh definitely not. But its not bad in its own right. It's not backlit, it uses ambient light to display the picture. So battery life is quite good. Personally I found it easy on the eyes, but then again I don't particularly have trouble with backlight LCD's for extended periods of time either.
The resolution of my 5'' is 640x480. The size definitely kills it for anything other than standard novels. If they came out with an 8inch version I would be all over it.
