If I recall correctly, Microsoft promised us a “Windows Everywhere” experience that is quite consistent in its nature, especially when it comes to the user interface. So far, it’s been “modern UI” and tiles everywhere but sadly that is as far as the consistency goes.
I’d love to see the same live tiles everywhere. I’d love to see my own settings and accounts being brought up from Windows 8 to Xbox to Windows Phone. I’d love to see the same apps available in all Microsoft platforms. More so, I’d love to see consistency in developing apps for all their devices so that developers can easily deliver the same apps across many Microsoft products. That’s the “Windows Everywhere” experience that I am anxiously waiting for.
