"Now that we know how the iPhone 4S stacks up against the iPhone 4, let's take a look at how Apple's latest smartphone compares to its mightiest competitors on the other major platforms -- Android and Windows Phone. In Google's camp we chose the superlative Samsung Galaxy S II models (focusing on the announced US variants) along with the Motorola Droid Bionic for its qHD and LTE chops. We then picked the upcoming HTC Titan to bat for Microsoft's team. RIM's not included here since it's still stuck in the junior leagues. We left out the intriguing Nokia N9 because it's a niche player. Check out the fancy table after the break -- the results are pretty clear cut!iPhone 4S                Samsung Galaxy S II                Motorola Droid Bionic                HTC Titan                                      Platform           iOS 5           Android 2.3.4 with TouchWiz 4.0           Android 2.3.4 with custom skin           Windows Phone 7.5 Mango                   Processor           Dual-core Apple A5 (likely 1GHz)           1.2GHz dual-core Samsung Exynos or 1.5GHz dual-core Qualcomm Snapdragon S3           1GHz dual-core TI OMAP 4430           1.5GHz single-core Qualcomm Snapdragon                   RAM           Unknown (likely 512MB)           1GB           1GB           512MB                   Storage           16GB / 32GB / 64GB internal           16GB / 32GB internal, microSDHC expansion           16GB internal, microSDHC expansion           16GB internal                   Cellular           Quadband GSM, quadband HSPA+ 14.4, CDMA / EDVO Rev.
