Several days of use impressions (PRS-505): That firmware completely killed my wishes to get new device. It is simpler than original and having less features than PRS+, but for me providing the most needed changes - not buggy sd card operation with cyrillic file names, no 20 min wait for the scanning, reading while charging, fb2 support (bye lrf), fast book opening and font changing. I think I'll be using this reader for at least 3-4 more years
