Whilst Windows 8 is great on a tablet, the desktop experience leaves a lot to be desired and power users find themselves primarily using the desktop.
Having created the excellent Start8 utility to give Windows 8 a proper 'start menu', StarDock have gone one further with 'ModernMix', which allows you to run Windows 8 'Modern' apps in desktop windows.
This allows you to display and pin the apps to the desktop taskbar, gives you the normal minimise, expand and close buttons, and remembers the window size the next time you launch the app.
In other words the Windows experience we know and love and so much easier for desktop users.
