Yes... I sort of came to the conclusion about PDFs - might just as well use one of my tablets (I embarrassingly have a few to choose from).
Any idea on if the new Kindle ereader has any outstanding innovations? I guess I went through all this effort to get the current Kindle Touch (on sale, handled a whole scad of ereaders), so I'm a little reluctant to part with it, although I might kick myself when the new one comes out! I'm surprised there have been very few details leaked...
