Finally, Amazon refreshed its original e-reader, the Kindle, with new features and a lower price.

The new Kindle price is $69 and available for pre-order today. It now has new fonts, sharper text and 15 percent faster page turns.

Immersion Reading

No more robot voice narration, with Immersion Reading, Amazon will offer professionally read audiobook components for major titles.

These will be read by actors, and will allow users to go between text and voice seamlessly.

Amazon's presentation showed actors like Samuel L. Jackson and Anne Hathaway reading bestsellers.

Whispersync for Voice and Games

Whispersync, the feature that keeps your place in whatever you're reading across Amazon devices, will now work with games and e-book Immersion Reading narration, on the Kindle Fire HD or a smartphone with the Audible app. You'll be able to pick up right where you left off by reading text or by listening.

Kindle Fire HD

For gaming, Whispersync on the Kindle Fire HD will now back up your progress, letting you continue at your last checkpoint, and keeping track of your scores and completed levels.

Kindle FreeTime, parental controls at last

This should help household negotiations. Parents will now be able to create individual profiles for their children, and limit what they can do on a Kindle Fire HD.

Parents can set individual time limits for activities like reading, watching videos and playing games. It can all be tweaked, so you can rig the device for your children to have unlimited reading time, but only an hour or two of game time a day.
