On and off I've been blogging on e-books and dedicated e-book readers. In the random way one does I stumbled across Stanza, an e-book reader both for the iPhone and the desktop.
I've yet to try the desktop version, but I installed the iPhone version on my iPhone (where else), downloaded a copy of Tacitus's Germania from Project Gutenberg to try.
Basically, it works, the font is clear and readable and the 'touch right to go forward, touch left to go back' interface is natural and intuitive. Like all electronic displays you have to get the angle right to read it easily, but then it's easier than a book to read in poor light.
Basically it looks good and worth playing with some more ...
