Kobos let you install custom book-reading software without too much hassle. KOReader[0] is the most popular one. I like it because it allows for a ton of customization, can properly render pretty much any EPUB you throw at it (much better than stock), and can reflow PDFs (using K2pdfopt[1] under the hood). But there are some other alternatives, including Plato[2] (simple, easy to use, fewer features) and PBChess[3] (closed source, play chess on your Kobo). The MobileRead forums[4] are quite active, you'll find a lot more there.
