Thank Apple and the big six publishers for their collusion in fixing e-book prices and coming up with the agency model for ebooks. Pet peeve of mine too, but long term it's going to be the big six's downfall.I love both! I have a Kindle, which I adore, especially for travel - I used to go on holiday and come back with four or five books stuffed into my suitcase after a week. Plus, it's light and compact, so I can read it one-handed on my commute to work (note: I do not drive to work!)
On the other hand, it annoys me how most ebooks are the same price, if not more expensive, than their papery counterparts. You'd think they'd be cheaper because they don't have to be physically produced and distributed. And I love the smell and feel of books, so I'll always have them. They'll just travel less.
