BLU vivo Air : hands on

Every year, it seems like we say, “OK, our smartphones are thin enough. Let’s give this race to the bottom a rest and focus on something else.” And every year,manufacturers still manage to release some super-thin smartphones that, despite our protestations, end up leaving us wowed at these feats of engineering. Now the latest push is towards hardware that skirts the 5mm-boundary , and at CES 2015 we got to check out one of these devices in the flesh, the 5.1mm-thick BLU Vivo Air.The Vivo Air may not directly compete against quad HD,4GB RAM monsters, but there’s still a lot of hardware inside this smartphone: a 4.8-inch 720p display,8MP main camera with 5MP front facing camera, and a quad-core 1.7GHz SoC. Storage only hits 16GB, though, and the single gb of RAM may have you wishing for more.Really, with a phone like this we’re most interested in how it looks and feels, not how every last internal spec measures up. Is 5.1mm just absurdly thin, to the point that the handset’s a bit awkward to use? Or does a build this petite actually work for the Vivo Air, giving the hardware a touch of class that might be missing from a larger model? Watch our hands-on below to see just what we thought of this wisp of a phone.
