Barnes & Noble is playing with fire — Kindle Fire. On the heels of Amazon's Kindle Fire HD announcement , the brick-and-mortar book retailer introduced the new Nook HD and Nook HD+  this week, boasting the "world's highest-resolution display on a seven-inch media tablet" and the "lightest, lowest-priced full HD tablet" on the market. Barnes & Noble's new offerings — the Nook HD 8GB ($199), Nook HD 16 GB ($229), Nook HD+ 16 GB ($269), and Nook HD+ 32 GB ($299) — are available for pre-order today.
Both the Nook HD/HD+ and Kindle Fire HD include Bluetooth and Wi-Fi support, run on a custom Android 4.0 Ice Cream Sandwich operating system, and are tapped into massive selections of books, magazines, and video. So what sets the latest contestant in the tablet competition apart? Here are eight distinctions between the two competing high-definition tablet ereaders.
Slightly taller and thicker — The new Nook HD is 7.65 x 5 x 0.43 inches (HWD), versus the Kindle Fire's 7.6 x 5.4 x 0.4 inches.
Higher-resolution display — The Nook HD 1440 x 900 display bests Kindle Fire HD's 1280 x 800.
Fewer bytes for your buck — Both priced at $199, the Nook HD comes with 8 GB capacity compared to the Kindle Fire's 16 GB capacity.
Lightest in its class — The Nook HD+ is a lightweight at 11.1 ounces, whereas the hefty Kindle Fire HD comes in at 13.9 ounces.
No camera — The Kindle Fire HD has a front-facing camera, while neither the Nook HD nor HD+ have a camera on board.
Fewer apps — Amazon's app store holds over 50,000 applications for Kindle Fire, and Barnes & Noble's app store has a mere 6,000.
Free power adapter — This may seem like a given, but the Kindle Fire HD does not come with a power adapter to charge the device; it must be purchased separately. The Nook HD and HD+ both include a free adapter.
