Given the Nexus 7's better-than-average feature set, Google could have charged $249 for its tablet without incurring much wrath from tech pundits. But the Nexus 7's impulse-buy-inducing $199 price should make the slate a popular item this holiday season. With its front-facing camera, (relatively) high-resolution screen, quad-core processor, and 12-core GPU, the Nexus 7 has the $199 Kindle Fire beat--well, on paper, at least. But how will the Nexus 7 stack up against Amazon's second-gen tablet? We'll find out soon enough.
