I have been loving my DX since Xmas, and as a former Sony Reader refugee I cannot tell you how much I do not miss needing to run my technical documents and research papers through this sort of PDF munging in order to get something that is (barely) readable on the smaller e-ink screens.  If you read a lot of technical books, papers, or other docs formatted for A4/8.5x11 then do not consider any of the smaller e-ink units.<p>The page turn speed is not fast, but since I was used to it from my previous e-ink device I don't find it too much of a bother.  The thing that you lose from a physical book is the ability to scan quickly to a particular section that you then drill down to the page you want.  With e-ink you guess the approximate area and then guess a couple of more times until you get to the right page.  The biggest "fix" that could be provided in this case would be for hyperlinks within the doc to work so that you could bounce from the table of contents or index to a specific page.  At least with the DX I can actually go to the page I want though, with reformatted docs on a smaller display (like the use case for the OP software) there was no match between the original page numbers and the actual page number on the reader, so it was a real PITA.<p>Short version: if you read technical docs or papers in PDF format do not consider anything smaller than a DX or iRex.
