I don't have my Iliad for a long time so I'm still a newbee
I have a Platinum 1 GB SD card which works OK, only when reading for 1-2 hrs. I did notice on 2 different books so far (prc, mobipocket) when I flip to next page it goes up 20-30 pages.
I know when I press the turn page scroll longer it jumps 5 pages for or back that's working ok.
I assume now that it might be a matter of the SD card, means when loading it makes a mistake or is the whole ebook buffered in the Iliad memory when reading?
What do others use the MMC / SD or a CF card ?
