An hidden gem
BEST ebook reader on iOS, by far. Full support (search, annotations, bookmarks) both for PDF and ePUBs; PDF support for cropping and pretty good text reflow; shares book notes on Evernote, pretty decent interface. It appears to be a bit asian-centric (all books in embedded store are in chinese -I think) and define worda automatically leads to chinese dictionariesm (I'd love if you could set the language for that), but they're definitely minor gripes!
