Back after a month or so of using it. It is still the best ebook reader I have used (and I have used a few, both on PDAs/smartphones and on desktops) because the authors have taken a great deal of effort to present books clearly. I was surprised, on briefly using an Amazon Kindle, to find out that Gutenberg texts are presented as they are input, with no attempt to clean them up.
The previous commentator is misguided because there is a big distance from a raw ASCII file downloaded from Project Gutenberg's Web site to something which is reasonably pleasant to read on-screen; all texts contain lengthy doses of boilerplate legal and licensing information and, especially with older text, hard formatting (chapter headings, page headings, page numbers, tables of contents etc.) which takes no account of the actual screen size and looks dreadful on anything not 80x24 (?) characters. As well as the hyphenation bug noted earlier ...
I mark Voluminous down slightly because I still feel it is a bit expensive and because the new output to text file outputs the original Gutenberg text, not the parsed and cleaned text (which shows how untidy the raw text frequently is!) - a slight annoyance.
Now ... can we have an Apple ebook reader?
