Yes, once loaded everything is fine. But when you resize the window or change the font size it gets really slow. On VERY long books, this can take dozens of seconds.
I still believe though that the software could be faster... It doesn't take that long to open a LRF file on your Sony the first time. DE is really slow compared to this.
