The Sony Ericsson Xperia Arc S isn't a phone that blows us away. In fact, considering it's Sony Ericsson's current top of the line, it's a bit disappointing. There's no dual-core processor and the build is underwhelming. However, just as with the original Arc, the Arc S packs in the essential features, has a nice screen and a great camera. What's more it's available for a decent price, making it a sound investment if you're not after the absolute biggest and best.
