I'm guessing you are attempting to avoid an Apple computer or PC all together. While you can try, my bet is you'll have to be very agile and look for apps like the one in the link (or write your own.)

Is there a way to both download pdf files from the internet and view then on the ipad? I know that there are a variety of programs that allow you to view PDF documents but all the ones i have see involve using a computer to put the pdf files onto the ipad. Also the PDF files can only be accessed through a series of web portals with the original needing a login and password.is it possible access and download these through the ipad alone and then view and edit them and save them on the ipad? I need to be able to do this on only one device as i usually need to access research materials while on the go ( on the 2 hour bus ride ) and PDF is the academic standard for files.
