The Android reader wars are here in earnest now - Barnes & Noble just released their Amazon Fire rival with what's claimed a better spec in the battery and screen resolution department. Offering free WiFi at all its stores, the tablet will be widely available at the end of November 2011at a cost of $249. The spec compares well to the Kindle Fire with a 7-inch tablet, a 1024x600 pixel touch screen, 1G RAM an a Dual core 1Ghz OMAP4 CPU. This move is the next logical one for B&N who announced in the summer that the were selleing 3 times as many digital books through its websites as physical ones, and so pretty much had to do this to stand a chance of competing with Amazon, Apple etc.
