It
must be a reference to the ghosting, there's never been any indication that e-ink had that kind of failing. Even the Librie' didn't leave random pixels the wrong state, and these displays are a generation newer....
I'm increasingly satified that Sony has learned to play better with others; the SD card support, the TXT/RTF/PDF suport, mp3 & AAC file support ... it's pretty apparent that they're just not trying to lock this rascal down like they did the Librie'.
A very good thing that is for us.
