Red Rock,
Justifying the price depends on how much you read and how much you spend on books. I read about one large paperback per week (approx $15). Now I pay $9.99 or less, or FREE! So you multiply that by 12 and I come close to paying for my kindle in a year--definitely 2. This was amazing to me since my cell phone and laptop don't save me money in the long run.
