I have been using my K4 NT for about three + weeks. Loving it so far, especially battery life (amazing!). I had been using my tranny for ereading and had to charge it every other day. I've re-charged my kindle once, using it for an average of 1-2 hours per day.
The one thing I miss, and I've seen other topics talking about this so I know I'm not the only one, is the whole how long till the next chapter thing. The best way I've found to do this is:
1) Push Menu button (page number appears at the bottom of the screen)
2) Push Menu button again (close the menu)
3) Push the "right" arrow on the 4WC to jump to the next chapter.
4) Push Menu button again (page number appears at the bottom of the screen)
5) Push Menu button again (close the menu)
6) Push the Back button to return to the page you were on.
Which isn't horrible but is kind of a lot of steps. Is there a quicker way?

in advance for any responses.
