A couple of discoveries:
- when reading, opening the 'go to' panel shows the current chapter title and the number of pages left to read in the chapter
- when reading, to see title/battery status/time, tap center of the screen (but why not wireless status also?). Note the title hides after the first page turn.
- Nook and Kindle use the same type of USB cable, chargers are interchangeable. The perfect travelling companions!
