I liked my PRS-500. I thought it was a decent device, with so-so software. I didn't use it much after the first month or so. Then I got a Kindle. It more than doubled my daily reading and I still carry it always with me, several years later. In retrospect, I realized that I liked the PRS-500 just because it had the first good display I had seen for reading, but the software implementation, both on the device and the PC/store part were the bare minimum to make an "ebook reader" type device. I saw that some PRS-500/505 users gave it a little more life with Calibre later on, but that was not thanks to Sony. So I don't know about "hardware genius", was it perhaps before serious competitors started coming with devices which were at least on-par hardware-wise but had some brilliant ideas and software behind them?
