Taking on Amazon's Kindle Fire tablet, the Nook also comes with a 7-inch touchscreen display and runs a custom interface on Android 2.3 (no Android Market access). Under the hood is a dual core 1Ghz processor, 1GB RAM & 16GB storage (expandable). Battery life is a claimed nine hours and it weighs just 400g. It will be available towards the end of November, priced at about US$ 250
