Microsoft has a virtual keyboard for every platform, and they are all different. The Windows 10 keyboard, for example, lacks the swiping gesture of its older Windows Phone counterpart. On Android, its Hub Keyboard puts the focus on productivity and sharing documents instead. Its upcoming iOS keyboard, however, might trump all those, at least as far as smartphones are concerned. Called Word Flow Keyboard, this rather unique keyboard includes a special design intended for one-handed use, utilizing an arcing layout instead of simply shrinking the keyboard to one side.
