Agreed. I would add that number of "hours" only matters in the context of comparison with regular tablets AND the specific content that is being read.
For easy reads like Harry Potter novels, where people can zip through the pages there may actually be very little difference in terms of "books per battery charge" between an ereader and a tablet. For heavier content (like for example, a Stephen Hawking book), the reading speed tends to be a lot slower, and the power consumption advantage of ereaders become more apparent.
