I've been open to giving them a shot for a while but now that I've dipped my toes into the Amazon Kindle market place I've realized how nice it is. Gone is the daunting page numbers; replaced with percentages. It's much nicer, more modern.
The one thing I do miss is the feeling of a chapter and being able to flip back and forth as I wish. That hasn't been easy to replicate in my experience with eBooks. Maybe I should start using bookmarks more often when I feel lost or confused.
