Since both of you are using an SD card, I wonder what class they are. Are you using Class 2 (slow speed), Class 4 (faster), or Class 6 (much faster). This could make a dfference in the speed of loading. When you first load new books on the reader it will index them (I think) and that can take a while espicially if they are loaded onto a slow speed SD card. By indexing I mean index the words for searches.
