Like clockwork Barnes and Noble has outed new slates to compete head-to-head with Kindle’s new Fire tablets. There’s two of ’em, a 9-inch and a 7-inch, and they take aesthetic tips from their predecessors Nook Tablet and Nook Color, so let’s dive right in.

The 9-inch Nook HD+ boasts a full HD display (1920 x 1280 resolution, 256 pixels per inch) and it’s powered by a 1.5GHz OMAP4470 dual-core processor with 1GB of RAM. It’s lightweight at 515 grams and promises up to 10 hours of reading and 9 hours of video playback. As far as ports go there’s a 3.5 mm stereo headphone jack, one HDMI-compatible port, microSD, and a charging port. WiFi 802.11b/g/n and Bluetooth are built-in. It comes in a black “slate” color in 16GB ($269) and 32GB ($299) storage variants. The HD+ is up for preorder today and goes on sale in November.

The 7-inch Nook HD packs a 720p display (1440 x 900 resolution, 243 pixels per inch) and it’s powered by a 1.3GHz OMAP 4470 dual-core processor with 1GB of RAM. It’s even lighter than it’s more powerful sibling at 315 grams and its battery promises nearly the same life expectancy. The ports, expanded memory, and wireless connectivity remain the same. It comes in not one but two colors–black “smoke” and white “snow.” The 16GB models will sell for $199 and the 32GB models will go for $199 when the HD releases this November. Like the HD+, it’s available for preorder today.

So if you’re in the market for a new device that delivers reading experiences (books, magazines, newspapers), video and music playback, and apps, the competition (read: Google, Amazon, Apple) just heated up.
