Just sharing: I've recently downloaded Moon+ reader on my android and I just want to say its amazing for those of you who may be looking for an ereader or just want to update to a better ones. It supports epub, mobi, txt, html, umd, fb2, chm, cbr, rar, zip, opds and (pdf- pro version only). Customization is amazing and the features are endless. O and if you happen to open a format it doesn't support such as .doc or .docx it automatically reroute you to a program on your device that does support that format and opens it for you. Check it out, its amazing.
