iPad and PDF scans

Normally handles. Advise program GoodReader, it is optimized for reading PDF files of large size: itunes.apple.com/us/app/goodreader-for-ipad/id363448914?mt=8

Pro PDF 100 megs.
I have downloaded iBook in me a layout of the photobook in PDF 82 MB.
When quickly scrolling to "brake" the most minimal.
You could even say that I pick rather than have a real problem.

About Djvu to advise you to buy xDjvu — is inexpensive (I took the discount — 0.99), read the truth on the iPhone — but big enough scans (opened for 60 meters) — leafs normally (before she tried the other three, one of which took over 5 bucks — brakes are. that is difficult to read)

To view a pdf advise of DropBox, free. However GoodReader can display on an external screen, but costs money. Earlier there was a problem with the display of jpeg2000 images in pdf, but at least GoodReader ee fixed.

djVu reader I have put offers, but not used even once for some reason.
Basically Epub and PDF.
By the way, native Mail client right out of the box well opens different documents from MS Office, at least Mordovskie formats accurately. What a great surprised and pleased me!

PDF read the usual iBooks. Awesome!
