Lexcycle released a new version of their Stanza reader that is optimized for iPad over the weekend. (Actually, there is a single app that works for iPhone/iPod touch/iPad.) The new version not only takes full advantage of the larger iPad screen, it has also added support for PDF, DjVu, and Comic Book Archive (CBR and CBZ) files in addition to the ePub and eReader files it already supported. You can even drag files from iTunes and drop them into the “File Sharing” section of the “Apps” tab on your device. Stanza is free in iTunes now.
