CloudReaders alternatives

CloudReaders (TM) is a free book/comic/movie viewer, fully optimized for iPad (and now supports iPhone/iPod touch too!). It supports PDF, CBZ, ZIP, CBR, RAR, MOV, MP3, M4V, MP4 and 3GP format. It allows you to read any book/comic files in either PDF, ZIP/CBZ or RAR/CBR format transferred from your PC/Mac or downloaded from the Internet. CloudReaders also comes with a "cloud bookshelf", where you can download public domain books and comics for free (the number of books is small at this moment, but we are going to add a lot of books soon).
