I'm looking for an app that will read non-DRM'd epub, mobi, PDF, and comic (cbr/cbz) formats.

Sadly there is no such thing like one-fit-all solution.

Reading HTML, txt, or rtf/doc would be a nice bonus, but not necessary.

Sigil and perhaps other programs also, has the possibility to add a HTML file and text file can be past into a Sigi EPUB file.

I'm hoping to find the ereader device features I care about:
- Remembers where I left off in each book
- Has a library that works offline
- Sort by title or author, and ideally by recently read/recently added
- Ideally, looks at metadata and not filename
- Add bookmarks easily

Look to a program which requirement are fulfilled by each program

Although at this point, I may settle for "opens the filetypes and doesn't mangle the epub or mobi formatting."

The advantage of each standard is that it is not quite the same as another standard. The result is that something always goes wrong with a conversion between different standards. You must either accept that or correct it manually.

A PDF can be the output result of many different programs. With search and replace you can remove a lot of superfluous junk, but in practice, converting a column layout for example can produce a dramatic amount of work.
So it simply means that you have to settle for a lot of different programs or do a lot of manual conversion work to convert everything to your favorite program.
