Oh, and e-books, of course. Lest we forget, books were the original Kindle's raison d'etre, and the Fire makes for a mighty fine e-reader.
Just one problem: You already own a bunch of e-books purchased from Barnes & Noble. Or perhaps you have Nook-using friends and family members who want to loan you some great reads, but can't because you have a Kindle. Heck, maybe Barnes & Noble's "Nookstore" is running a killer promotion on e-books, and you want to jump in.
What you need is a way to run the Nook app on your Kindle Fire. That would open the door to past and future B&N purchases, as well as books loaned from other Nook owners.
Unfortunately, Amazon's Appstore doesn't carry the Nook app, for semi-obvious reasons. So what's a voracious reader to do?
Simple: Work around Amazon's restriction. You can do this by installing the Nook app from a different source. It's harmless, legal, and fairly easy. Here's how.
1. Tap the Settings icon in the upper-right corner, then tap More, then Device.
2. Enable the "Allow Installation of Applications" setting (i.e. turn it on), then tap OK when you see the warning that appears.
3. Open the Fire's Web browser and go to m.getjar.com. (GetJar is another app store for Android apps.)
4. Search the GetJar site for "Nook," then tap the Download button. You'll see a request to download the GetJar app, which is required. Tap Download GetJar.
5. When it's done, access the Kindle's downloads list (via the top bar), tap the GetJar file, and choose Install.
6. Now run your new GetJar app, search for "Nook," and then tap Install.
Presto! Now you've got the Nook app on your Kindle Fire. Run in, sign into your account, and you're good to go.
Note: Some users have reported that the Nook app doesn't appear when searching inside the GetJar app. In that case, go back to the Fire's browser (Step 4) and try searching the GetJar site again. If that doesn't work, here's another tutorial for installing the Nook app on your Kindle Fire.
One last thing: If you want to read Kindle books on your Nook Color or Nook Tablet, the easiest solution by far is a Nook to Android card from N2ACards. Pop it in and presto, you're running Android—and all the apps you can tap (Kindle included).
