The first of many Xperia-branded phones to debut in 2011, the Arc sports a new display technology called the Mobile Bravia Engine. The Xperia phones have been slightly disappointing in the past because of their sluggish performance.
Like the other Xperia phones, the Arc looks beautifully designed. It is also exceptionally thin at 0.34-inches in diameter. The 4.3-inch display is designed for entertainment-hence the shared name to the company's line of HDTVs.
