Just a quick update - after doing some reading with Calibre, I'm still on the hunt for a Win 8.x eReader app. It certainly *works*, but I've grown used to a more fluid and natural *touch* eReading interface than what Calibre provides
Not a ding on Calibre at all, Kovid has never made any bones about not being touch-oriented, and I *love* the management application. I'd previously always used something else (dedicated device, app on iOS, whatever) for reading so hadn't really paid much attention to the Calibre eReader itself. I'm not even sure how to quantify what I dislike about it, but I'm still looking....
