Amazon has had great success with their Kindle Fire line of "Android" tablets in the past few years. They are the originators of driving down the tablet prices. This year, Amazon introduced us to the Kindle Fire HDX which has amazing specs and comes in 3 sizes (although only the 7-inch and 8.9-inch are available right now) as well as in 4G LTE for AT&T or Verizon. The 7-inch Kindle Fire HDX starts at $229, and the 8.9-inch starts at $379, and go up depending on if you want LTE connectivity or more storage.
I actually reviewed the Kindle Fire HDX 8.9-inch earlier this month. I was actually quite impressed with it, even though it doesn't have any Google services. The Kindle Fire HDX features a Snapdragon 800 processor, along with a 2560×1600 resolution display on the 8.9-incher and a 1920×1200 on the 7-incher. The hardware is amazing on these tablets, especially considering the price.
The Amazon Kindle Fire HDX is a great gift for those that heavily use Amazon's services. Like Amazon Prime, Instant Video, etc. The Kindle Fire tablets are just a window into Amazon's store, which is why they sell the Kindle Fire HDX's for so cheap. In fact, they lose money on the hardware. Similar to Google, except Google breaks even on their hardware. You're also stuck with the Amazon App Store and not Google's Play Store. So this may not be the right gift for anyone reading this, but for those that just want a tablet to play some games, check Twitter, Facebook, etc., or read some books, this is a great gift. And the price is right as well. Not to mention Amazon's Mayday feature, which is 24/7 live support from Amazon, which is a great idea on Amazon's behalf.
