I have used Lithium Pro for years and read 100s of books with it. I have and at times used other readers, but Lithium is my go-to day in and day out. It is rock solid. It's configurability is not as extensive as some others, but the configurability available is perfectly chosen and easily accessed. This is important as I read in different environments so quickly adjusting font intensity or background color is very useful - I do such frequently. Lithium is the most usable reader I've found!

generally not a bad reader; I like the simplicity, but the underline/highlight feature is atrocious. Keeps marking multiple lines across multiple pages at once thinking I'm flipping them, whereas I'm obviously not. it's a huge waste of time. hope this will be addressed at some point.

Great E-PUB reader app, solid and intuitive interface. If I had a gripe, it would be that there could be a bit more categorizing options. Being able to edit the book flags. Example: sorting by author name, but some book files have first and last name reversed. This throws of the sorting order. (Brooks, Terry versus Terry Brooks)
