OK, before going to bed: David, I took you up on your offer to download one of the large PDFs & try it on the DR1000.
However, and I hope this is not causing you too much trouble, I went with the 175mb one since we already established here that the one you asked about works fine.
So: the reader can handle a 175mb PDF file! That's larger than the built-in memory (128mb)!
It took quite a while to load it initially (a couple of minutes), but after that I was able to flip to any of the 1250 small print pages in under 10s. Straight ahead reading, after some caching, was nearly instantaneous. I was even able to zoom in at 200%. At first I got an out of memory error, but then it displayed the next page anyway. Panning was slow... obviously. More importantly for you, I think, is the ability to search in such a text: that works too, albeit rather slowly!
All in all, I'm quite impressed. But it also proves once again that the size of the PDF itself does not play nearly as big role on how it performs than the contents itself, esp. graphics.
I'll get rid of it as soon as there no other questions, it's not my idea of light reading anyway
