This is a pricey app that is difficult to cancel. Its fine for reading but really, Ive got better less expensive apps that dont require me to battle customer service on the regular. Good Reader is my favorite reading app because it allows me to mark up the pages like they were paper. Its a one time fee. Its just up to me to locate the PDFs to upload there. Finding PDFs isnt that hard. But if you like paying $100/yr for an ok app, by all means, get yourself some Scribd.
