I have tried the Surface, and been using Windows 8 and Windows Phone for over a year. On the other hand Marco tried it for a couple of minutes, and arrived at a hasty conclusion without even giving it a fair try.

It is a completely different approach to iOS and Mac. And it is better. I can safely say Windows 8's Metro UI is miles ahead of Apple's iOS in terms of UI and UX. Metro UI is prettier, easier to use and by far more productive. Apple's iOS looks static, dull, ancient and boring compared to this.
