This is all you need to know from the review (besides the crappy, slow and laggy OS) :
"... the Fire HD can at times feel like the most blatantly pushy, consumer-focused, retail-oriented device ever made. There is no shame in what Amazon is doing nearly everywhere that content lives on the device, the company is trying to push you towards more content. Even in places that might be considered sacred, like your homescreen (a view you see most often), there are breadcrumbs to get back to the store for more buying. And that's to say nothing of the full-screen lock screen ads, and subtle, sneaky text ads that populate the corner of the device"
You might as well turn your tv on and watch QVC or HSN. Only difference is, the tv will recognize when you push a button on the remote and won't freeze every time you change screens.
