Usability 
I think BooksInMyPhone is a great name The site at mobile.booksinmyphone.com offers a small but growing collection of out of copyright classics and Creative Commons titles. The mobile site lists about 200 books in various categories. There is no search box, finding a specific title means a trip to the PC site, BooksInMyPhone.com to get a download code and then back to the mobie site to key in the code and get the download. The codes are alphanumeric too, a numeric code would be easier to key on the phone. That might be tolerable if the reading experience was good. Unfortunately the reader software is slow at paging down which interrupts the flow of reading. The real show stopper is that the left and right directional pad keys jump to the previous and next chapters. I'm always absentmindedly hitting the right key which I'm used to using to page down in Opera Mini and gMail and ending up in the next chapter. That wouldn't be so bad but when I press the left key to go back it takes me to the beginning of the previous chapter and I have to slowly page down to find my place. Update: a reader points out that you can press the "up" key to go back to your place in the previous chapter. BooksInMyPhone's also creates whole books as a single file regardless of size. Many novels are over 200KB when packaged as Java books. Few feature phones can handle jar files much over 100KB so any substantial work will be too big to load on the majority of phones.
