The Sony works?
I REALLY hope it works better than the old 500 model...
When listing .PDFs, it ONLY uses the title as found in the document, not the filename, and frankly when you have heaps of files listed as 'chapter 1'(or variations of that), 'Index' or 'Preface', it doesn't make for much user friendliness....
And displaying .PDFs?
Unless they've been created for A5, they're just not readable.
But maybe the 505 is better?
Mine's the one with a Psion netBook(with PDF+ installed. At least THAT program has a zoom function)
