The Kindle Fire HDX 8.9.

Amazon's tablet lineup for 2013 is now complete, following the release of the Kindle Fire HDX 8.9, a bigger version of the new 7-inch Kindle Fire HDX that launched last month.

You can buy it now starting at $379.

The differences between the 7-inch and 8.9-inch models are about as subtle as the differences between the iPad Air and iPad Mini. The Kindle Fire HDX 8.9 has the same software, apps, and services as its little brother, but packed into a bigger body.

So I'm not going to spend a lot of time going over the same stuff I did in my last Kindle Fire HDX review. Instead, it's more important to focus on what sets the Kindle Fire HDX 8.9 apart from the smaller model and the rest of the competition.

Big Screen, Light Body

I've grown to become more accustomed to the tiny tablets, but in this case, I like the Kindle Fire HDX 8.9 a little better than the 7-inch model. It has all the same design schemes, but it's incredibly light for a full-sized tablet. At 0.82 pounds, it's only slightly heavier than Apple's iPad Mini with Retina display, and noticeably lighter than the new one-pound iPad Air.

That's my favorite part about the tablet. It gives you the full-sized experience, yet it's light enough to use anywhere — in bed, on the couch, on the train — without feeling the weighty burden of other big tablets. Yes, part of the reason why the HDX 8.9 is lighter than the iPad Air is because it's slightly smaller, but I didn't miss the extra 0.8 inches of screen. That's a sacrifice I'm willing to make.

And the screen is gorgeous. It's technically sharper than the one on the iPad, but you probably won't notice a difference. One study said the Kindle Fire HDX has the best screen of any tablet. (I think the screen is great, but I'm not about to go through and count every pixel like others have. Just know you'll be happy with it.) Just like other high-res displays these days, images, text, and graphics look like they're printed on the glass. Movies, games, and everything else look great.

The HDX 8.9 is made out of plastic, but it's a high-quality, rubbery plastic that doesn't feel cheap or flimsy like some other mobile devices. It's not beautiful like the iPad Air, but it is perfectly functional. The only flaw in the design is that the volume and power buttons are on the back of the device, which makes them awkward to use. You'll have to develop some serious muscle memory to get used to it.

Amazon's World

The Kindle Fire HDX 8.9 is technically an Android tablet, but Amazon has modified Google's OS beyond recognition. Amazon stripped out all things Google from Android, meaning you don't get access to great services like Gmail, Google Maps, and the Google Play store for apps. (Yes, you can plug your Gmail credentials into the Fire's email app, but the experience isn't as good as Google's own Gmail app.)
