We humbly submit that the Xperia Arc looks and feels far more refined than LG's admittedly well designed Optimus 2X. The Arc's curvature seriously makes it feel like the thinnest phone we've ever handled and its weight is also dramatically, unreasonably minimal. Another note of import is that the 2X comes with a 4-inch screen whereas the Arc offers a more generous 4.2-inch display, yet their overall dimensions are nearly identical. All in all, we'd hardly object to having either one in our pockets, but the Arc wins it for us in terms of aesthetic appeal. Of course, the Optimus 2X has a dual-core Tegra 2 heart beating within, it's not all about looks, though in the case of this hands-on comparison, it kind of was. We'll have a full review of LG's handset in the coming days, while Sony Ericsson promises the Xperia Arc will land in Europe by the end of March. You can see more of the prototype unit we got to handle in the gallery below and there's a video comparison of the two Android newcomers after the break as well.
