Google has unveiled the Nexus 9, an HTC-made tablet that will run Android 5.0 Lollipop. Curiously, there's an 8.9-inch 2048x1536 display -- 4:3 aspect ratio, rather than the customary 16:9 -- and also BoomSound dual front-facing speakers. Inside the Nexus 9, of course, there's Nvidia's 64-bit Tegra K1 SoC. Pricing starts at $400 for the 16GB model, and it'll arrive in stores (in the US) starting November 3.
