Re: Leave you longing for Windows 8...
Because you never used a Surface or the like, maybe. W8 *does* work well on touch input devices if you use them with well designed "modern" apps. The problem was forcing that on desktop users and desktop applications, where it does't work well at all.
Now going back and forcing a more desktop like UI to tablet users is another mistake - it's incredible they can't understand different modes of use needs different UI paradigms, there's no one-size-fits-all.
