Windows 8.1 is pre-installed on the Surface 2 4G – with Office Home & Student RT and Outlook RT - and like the Wi-Fi only model, it comes with an nVidia Tegra 4 processor and a 10.6-inch ClearType Full HD display.
Importantly though, it adds a micro-SIM card slot which is capable of offering 4G LTE mobile data connectivity 'allowing more people to stay connected and be even more productive on the go'. The 4G model of the Surface 2 only weights 10g more than the Wi-Fi only model.
Microsoft said that "new customers will receive free Skype calling to landlines in more than 60 countries for one year, unlimited Skype Wi-Fi available at more than 2 million hot spots worldwide for one year, and 200 GB of free OneDrive storage for two years."
The software giant recently announced thatWindows will be free to manufacturing partners for 9in devices and smaller at its Build 2014 developer conference.
