See this link for the Consumer Reports review of the Amazon Kindle HD:
""The Amazon Kindle Fire HD may not meet the company's goal of creating 'the best tablet at any price,' our tests suggest. But it's a fine performer that improves markedly on the first-generation Fire," reads the site's review
It is a vast improvement over the Kindle Fire 1st Generation but not quite up to an iPad yet. Its supposed to have 8 hours of battery life before a recharge.
