I recently got a MSI Wind--lightweight laptop with a 10" widescreen display. It's perfect for reading comic books in .cbr format, and seems like it should be perfect for ebooks, too, but I haven't found a good program.

Minimum, I need a pdf reader with "fit" options for fullscreen (fit height, fit width, best fit, etc). Ideally, I'd like something that can handle the various file formats, or a fairly active open source project, so that eventually it will handle all the formats, and is designed with a book-like experience in mind.

I hadn't paid much attention to ebooks or pdf readers before I got the Wind, so there may well be a common app I'm not aware of.

Any suggestions?
