Microsoft has built a ton of new features and capabilities into Windows 8 that make it a prime OS for mobile devices like ultrabooks and tablets. Aside from the Metro UI that is designed to be tapped and swiped on a touchscreen display, Windows 8 also includes new features for connecting to and managing mobile broadband connections.

My four year old Dell XPS M1330 laptop has an AT&T SIM card and built-in 3G mobile broadband capabilities. At the time, that was fairly cutting edge, but now it is almost a requirement. There are public Wi-Fi hotspots available across the United States, but there are also still vast areas with no Wi-Fi, but plenty of 3G or 4G mobile broadband signal.
