Kindle Fire HD Review is on the mind of every consumer considering the purchase of a new tablet. Kindle Fire HD and the new e-reader model, Paperwhite, were unveiled by Amazon on their Sept. 6 conference. The tablet is a new and improved Kindle Fire with high definition in an 8.9 and 7 inch model. Google Nexus 7 is similarly impressive and comes in an 8GB and a 16GB model.
