MobileSheets never loads more than 7 pages forward, and 4 pages backward into memory. For some tablets, even that is too much, so I have to reduce the number of pages that are buffered after an out of memory error occurs. You can load a 741 page PDF, but I certainly don't put all 741 pages into memory, as that would certainly drain all the available memory and cause out of memory errors.
