The 4.2-inch screen is bright and lucid, though we'd warn against expecting too much from the Bravia Reality Display marketing. As we've mentioned before, the display enhancements only kick in when you're consuming multimedia. Still, general performance looks more than satisfactory. Hard buttons around the body are well arranged and designed, a contrast from the fiddly keys we found on the Xperia Pro. What was consistent with the rest of Sony Ericsson's Xperia crew, however, was the Arc's inability to execute its pinch-to-zoom widget summary screen. It's an ambitious function -- gathering all your widgets from each screen into one cohesive overview -- but, basically, it's laggy as hell. Aside from that, general UI responsiveness could also stand some improvement, but we like where Sony Ericsson is going with the whole thing. If it keeps up its promise to repent from last year's sins with relation to Android updates, the company has a very good chance of striking it rich with the Xperia Arc. It's a phone that can truly get by on its looks alone. Video after the break!
