I've had it with e-Book Reader. I am using an 8 GB card with my PRS-700 and have almost 1500 books or documents on it. The e-Book Reader can't handle it...love the PRS-700, hate the software. It rarely syncs; most often just freezes up -- its a crap shoot. So, I switched over to Calibre and was immediately able to download some new books. First impressions are positive. Now my question is, will Calibre allow me to manage my books by collection? I haven't found that feature yet. And, will it synchronize -- automatically saving changes to both the PRS and Calibre? Thanks.
