So, other than a "lag fix" that both Samsung and independent developers are working on, the SprintSamsung Epic 4G (a Galaxy S phone) is remarkably fast. (We’ll talk more about that in an upcoming article.) How fast is it? In this video we look at a hacked Google Nexus One running a super-fast Froyo ROM with the stock Epic 4G. We look at overall interface elements (using the same Launcher app and similar widgets), side-by-side benchmarking, 802.11n data speeds, and 3G data speeds. Since the Nexus One doesn’t have 4G WiMax on-board this seemed a fair comparison.
