Gizmodo isn't much of a fan so far-
Barnes and Noble didn't let us listen to the 7-inch's speakers, but the 9-inch Nook was neither loud nor crisp, a noticeable drawback compared to the Kindle Fire HD. Despite stereo software that's supposed to give the impression of fullness of sound, it's still obviously coming from one side of the device.
The Nook HD doesn't look like premium tablet. It could be the tough-but-cheapy plastic exterior, or maybe the dorky hole at the bottom left of the 9-inch—as though it's crappy enough to just toss on a keychain or carabiner. The Nook HD has an aesthetically utilitarian design. It prizes screen quality and ergonomics. But it looks junky. And people just don't buy things that look and feel junky anymore, no matter how good their components are.
B&N's horses can mostly keep up with the competition's books and comics and magazine offerings, but Kindle clobbers its new video outlet. There's no Amazon Prime bolstering people's free and owned content. And while Nook's got all the partners you'd want from a video store—HBO, Sony, STARZ, Viacom, Warner Bros., and Disney are all on board, so it's hard to go looking for something and not find it—it's just tough to imagine that many people willing to jump to a new ecosystem this late in the game.
