Like all good things Sony Ericsson, the Xperia Arc didn't wait for an official announcement to make itself known. First appearing on a set of teasing posters at CES in January, it confounded us with a ridiculously thin (8.7mm / 0.3in) profile and an unorthodox concave rear, whose sighting was followed up with the revelation of a potent mix of internal components as well. The same 1GHz Qualcomm MSM8255 processor and Adreno 205 graphics that you'll find on brandmate Xperia Play are present within the Arc, and are backed by 512MB of RAM (320MB available to apps), 8GB of MicroSD storage, an 8 megapixel Exmor R image sensor, an HDMI output, and a 1500mAh battery. That tightly packed interior is then topped off with a 4.2-inch Reality Display capable of accommodating 854 x 480 pixels. Throw the latest mobile build of Android, Gingerbread, into the mix and you've got yourself a compelling list of reasons for riding aboard this Arc. Nonetheless, spec sheets tell only half the story and we're here for the full disclosure -- what's the Arc like to use on a daily basis, how are its talents harnessed by Sony Ericsson's tweaked UI, and, most importantly, do people think better of us for carrying such a stylish phone? Keep reading to find out.
The Xperia Arc's physical design is very clearly targeted at fashion-conscious buyers. It's not ergonomically broken by it, but form has clearly led the way ahead of function (as illustrated by the camera lens being attached at the very top of the handset, its thickest point), but you know what, we don't really mind that. It's about time we admitted to ourselves that we buy phones as much for what they look like as for what they do, and we laud Sony Ericsson for having the audacity to pursue its target demographic with a highly distinctive design. Few things curb our enthusiasm as much as overly generic phones that try to be all things to all people and the Arc is commendably distant from that group.
Another important decision taken by Sony Ericsson is to equip this new Xperia with a 4.2-inch display, marking it out as the company's biggest Android handset to date and solidifying its credentials as an entertainment device. We generally enjoyed our time handling and using the Arc, which manages to fit within nearly the same dimensions as HTC's 4-inch Incredible S, but there is one significant flaw to its design we must point out: the back's curvature is going the wrong way. The Arc moniker wouldn't really make sense without the audacious concave shape, but there's good reason why the Xperia X10, Play, Pro, and Neo all have convex rear ends and it's that they simply fit better in the (human) hand. That's arguably the only concession Sony Ericsson has made in its pursuit of an aesthetically unique handset, but it does hold the Xperia Arc back from being one of the easiest-handling smartphones in the 4-inch-plus division. As it stands, it's merely very good, with neat curves wrapping around the sides and the aforementioned thinness and light weight (117g / 4.1oz) making it a pleasure to tote around.
Contributing to the diversity of Android key configurations, Sony Ericsson has opted for a trifecta of physical buttons on the Xperia Arc (the Back and Menu keys have swapped positions from the X10 arrangement), which are thankfully wide, easily identifiable, and highly intuitive to use. Aside from the good clicky responsiveness of each button, that's in large part down to the omission of the Search key, which we can't say we missed at all. Its absence paves the way for SE to center the Home button (a good thing) and generally simplifies a user control scheme that hardly needed to be quite so complex to begin with. The only downside to the Arc's buttonry is one we spotted with the Xperia Play as well -- there's no illumination for the key labels in the dark. You get a pair of lights marking the division between each key, but their purpose is basically indecipherable when the phone's used in the dark. An easily forgivable little foible, we'd say, on what is a very satisfying keypad.
The rest of the Arc's exterior is mostly uneventful, consisting of flowing, pretty lines, broken up by a volume rocker and MicroUSB port on its top left shoulder, a 3.5mm headphone jack directly opposite on the right, and an HDMI output and a rather tiny power / lock key at the top. There is a physical shutter button here, but it's positioned at the extreme bottom right of the handset, almost at the corner, which leads to awkward operation at times. Overall build quality feels robust and durable, though we're again under the impression that Sony Ericsson wasn't spending too richly in obtaining the construction materials. Nothing wrong with that for the most part, we don't begrudge manufacturers making savings where they don't cost the end product, but we did manage to induce a little creaking from the frame, particularly around the volume rocker.
