5 way Navigate - why not scroll ball?
I used to be a Blackberry user, and blackberry has a scroll ball for navigation. You can turn that ball to all direction effortlessly.
Why Kindle chose the square 5 way navigate instead of scroll ball? To get to any word for a definition, it means you have to navigate vertical for a few times, then horizontally a few times, it is so inconvenient.
This is so far the biggest drawback for Kindle 2.
Did I miss anything? Any tips you want to share for using the 5-way?
