Think iOS and Android are all that's around this holiday season?  Think again!  Aaron unboxes the Samsung Focus S, a second-generation Windows Phone device that's available now at AT&T.  It packs a 1.4 GHz single-core Snapdragon processor, 4.3-inch Super AMOLED display, 8-megapixel camera with 720p HD video recording, a front-facing shooter for those video calls (which you can now do in Mango), and Windows Phone 7.5.  It's a nice phone that closely resembles the Android-powered Galaxy S II line, but it's a pricey $199.99.  Will it sell well when you can snag the HTC Vivid or Apple iPhone 4S for the same price?
