Still pleased with this, especially the ability to take all the pdf's I want to read on a trip along with the detective novel for the way back without carrying a lot of paper.
The only major pdf issue seems to be that a pdf generated from a scan doesn't seem to work. The other slight annoyance is that if you are reading an epub book and then go to something else, the device puts you back on the page you are reading the next time you open that book. But for pdf, the device always puts you back at the beginning.
The lack of Hebrew support is annoying. Hebrew shows up fine in a pdf but does not show up in an epub book or in a word document. Maybe this will be taken care of in a future software upgrade?
The only other problem is my emerging addiction to the chess game that is included.
