BARCELONA, MOBILE WORLD CONGRESS — The Huawei Ascend P2 has appeared in a number of leaked photos in previous weeks, but at Mobile World Congress in Barcelona today, the device finally got its official unveiling. I got my mitts on the device as soon as I spotted it, and I was instantly impressed. Here’s why.

We’ve spent weeks drooling over leaked renders and rumored specifications for the HTC One, but at press events in London and New York today, the device finally got its official unveiling. Thanks to all those rumors, there wasn’t a great deal of surprise in HTC’s announcement. But nevertheless, the One looks like an incredible smartphone.

In addition to its 4.7-inch LCD display, which boasts a full 1080p resolution with 468 pixels-per-inch, the One sports a gorgeous form factor (one of the nicest I’ve seen on an Android device), a 1.7GHz quad-core processor, 2GB of RAM, and a new “UltraPixel” camera technology that captures around three times more light than than conventional 8-megapixel cameras.

Chinese electronics maker Oppo unveiled the Find 5, its latest flagship smartphone back in December, and it’s set to make its debyt in China later this month. The device will be available to pre-order from January 15, priced at ¥2,998 (approx. $485), and it’ll arrive on January 29. The handset is then expected to make its way to Europe and North America soon after.

After Sony’s new Xperia Z appeared on the show floor at CES on Monday, we were certain that the Japanese company would make it official soon after. And it’s now done just that. The Xperia Z is its latest flagship smartphone, with a 5-inch 1080p display, a 1.5GHz quad-core Snapdragon S4 Pro processor, and a 13-megapixel rear-facing camera.

We got a glimpse of NVIDIA’s new Tegra 4 back in December, when a leaked slide detailing its specifications began circulating the Internet. But the company has now made the impressive chip official at CES 2013 in Las Vegas. Designed for mobile devices like smartphones and tablets, the Tegra 4 boasts a super speedy quad-core Cortex-A15 processor and 72-core graphics, making it the “world’s fastest mobile processor.”
