As for the built-in browser, you can't even open your Favorites list when you're on a Web page. Instead, you have to navigate your way back to the browser's Starter page. And don't look for basic apps such as an alarm, task list maker or note-taker, because they're nowhere to be found.
Once again, to add apps to the Fire HD you have to use the Amazon Store rather than the Google Play Store, which means access to only around 30,000 apps. (Back in late June, Google announced that Google Play had 600,000 apps, and it has certainly grown since then.) Many useful apps are missing from the Amazon Store, such as Google Voice or Dropbox.
(There is a work-around for Kindle Fire HD users if you want to install some apps by downloading them directly as APK files instead of going through Google Play: Go to Settings --> Device and turn on "Allow Installation of Applications from unknown sources." However, most apps aren't available that way.)
X-Ray for Movies
Apart from the upgraded hardware, the biggest news about the Kindle Fire HD is its new features for watching movies and reading books.
X-Ray for Movies is particularly welcome. It integrates content from the IMDb website into the movies you play on the Kindle. As you're watching, you can tap the screen, then tap the X-Ray for Movies icon that appears to see a list of all the actors in the current scene. You can then tap any of the actors' names for more details about them, including their biographies, other movies in which they've appeared and more. And by tapping "See Full Cast," you can see a list of the entire cast and get more information about anyone in that list.
That's useful, but not as useful as it could be. The feature lists only the film's actors and doesn't offer access to IMDb's vast amount of other information, such as the director, writer, producer, cinematographer and other details.
In addition, X-Ray for Movies isn't available for every movie, and while it works with most new movies, it tends to be a hit-or-miss affair with older and foreign movies. So you'll find it's available for Casablanca, Citizen Kane and The Maltese Falcon, but not for one of the greatest musicals of all time, Swing Time with Fred Astaire and Ginger Rogers. As for foreign movies, Francois Truffaut's 400 Blows has it, for example, but his Jules and Jim doesn't.
New features for e-books
The original Kindle was first launched as an e-book-reading device, so it's no surprise that this newest member of the Kindle family includes several new features for enjoying books.
