No of course not hon. My library books however are DRM protected and use ADE they are in EPUB and the older ones in PDF.
I prefer FB2 format it's just a nice clean format I've come to use with the PP but libraries here use DRM.
It would be wonderful if a non painted V5 every came out. I would buy it without question and on the line with v6+ reader if it ever came back and the price drops.
Of course with Color E-ink coming out I may just hold off and keep using my peeling PP and my soon to be here Kindle 3 before buying another.
