Aaron reviews the Samsung Focus S, a new Windows Phone available on AT&T.  Specifications include a 1.4 GHz single-core CPU, 4.3-inch Super AMOLED Plus display, 8-megapixel camera with 720p HD video recording, a front-facing camera, 1,650 mAh battery, and Windows Phone 7.5 (Mango).  It's available at AT&T now for $149.99, placing it in a very competitive price bracket.  Is it worth purchasing, or should you spend the extra cash on one of the carrier's 4G LTE phones?  Part 2 of 2.
