Soluto’s report digs into how often people really use those apps on a daily basis.
The news isn’t wonderful. Of the 10,848 Windows 8 devices studied by Soluto, the majority of traditional desktop and laptop users—even ones using a device with a touchscreen—fail to open a modern-style app daily. (Note that this study refers only to modern apps, not to traditional desktop programs.) Even on tablets, the devices best suited for Windows 8’s modern UI, just 56 percent of all users launch a Windows 8 app day in and day out.
