2-for-1: Can Windows 8 satisfy both the desktop and the tablet?

Everyone's questioning Windows 8 because they see it as something that you're either forced to use in a tablet or forced to use in a computer, with possibly bad trade-offs in each scenario, and I didn't think much of Windows 8 either... until I saw the Lenovo Yoga.

Seeing an ultrabook that transforms into a reasonably compact, multi-touch tablet just made everything click. Windows 8 may not be the best tablet OS or the best computer OS, but it's the perfect OS for notebooks that transform into tablets or tablets that can be docked into a desktop setup.

But I wonder I all that Metro does can't be made throught Node.js too. I started some experiments about that.
