I downloaded Ansyr's Primer PDF viewer last night. This thing is amazing. Considering what it's doing, and that it's having to deal with the gross inefficiences of CE, it's one of the fastest apps I've seen. You can get it here: http://www.ansyr.com/products/primerwince.asp
Complex pages take several seconds to render (things like the Ferrari service or parts manuals, with their detailed illustrations, or the area code map I have that uses a lot of gradients), but text pages take about 3 seconds under 2.04 full. (Why such readers don't pre-compute the contents of the next page (and keep the results of the last one) so page-forward and page-back flipping is near instantaneous is something I've always wondered - after all, it's just sitting there while you read, why can't it be *doing* something?)
As a general rule, I don't buy software for personal use, but this program is one of the most useful additions I can imagine for the ePods. Highly recommended, and well worth the $50 registration fee if you want to use your ePods as a book reader.
Oh, and BTW, you can get thousands of books, even some recent ones, in PDF format at http://www.abika.com - I loded up my 32MB flash card last night with all kinds of good stuff from Jonathan Edwards to Robert Louis Stevenson to George Grant's excellent Grand Illusions. The quality of the Adobe Capture PDFs varies, but all are usable, if not so clean as we'd like. (Capture apparently just drops in the bitmaps for the things it doesn't recognize right away - not pretty, but it works.)
