This new tablet craze is already stealing the Kindle's spotlight. And that's likely to drive the price of these e-books even lower.
"There's a whole slew of low-priced tablets being released in April that will compete with the Kindle," said Pinsker. "They'll attach things to other versions to get more money, but for the basic model I think you'll be paying $99 by summer."
"It was destined to go to $99 no matter what -- this is the price at which point it goes from being a specialty item to something every single person has," she added.
