Hi Zonicles,
You're hit on one of the big hot points of e-book discussions. Every customer agrees that e-books should be cheaper than paper books, because of reduced cost to produce. However, it seems that publishers feel they are selling content and so it shouldn't depend on costs, but the value of what they offer.
Here's one interesting thread with some discussion (and you'll probably find many more here if you dig a bit)..
