I hope this helps.
a) Device ID: 4163 Rev: 326
b) I bought it in Canada and have done all my updates from Canada.
c) I updated to 2.0.0 over WiFi without any problems, but I did wait for the re-release of it. I can't remember what the factory version was.
d) I think all my issues have been reported.
- Slow page turns on side-loaded books. Kepubs are fine.
- Wrong book cover.
- Much slower start-up from power-off state.
- Font size is different between side-loaded books and kepubs. The font size in side-loaded books is much smaller.
- Word select seems slower.
The most annoying things to me about version 2 is the slow start-up and page turns. Shelves are nice, but if I'd known that I would have to give up performance to get them, I would have said "No thanks.
