Here are a couple of screenshots from my ipod touch. The only two downsides to using it for ebook reading is the small screen and the battery life which is only about three hours in my case even with the screen brightness turned almost all the way down.

I definitely recommnd Stanza over the Kindle for iPhone app. Kindle has almost no settings controls whereas Stanza has a few more including the ability to select a different font.

Note: With stanza you can email books to your Gmail account rather than using calibre. Then open your Gmail from within Stanza and download the file.

Attached screenshots: First two are from Kindle and last two or from stanza.
