I'm responding twice because you said so many interesting things here.
"Surface RT" is a touch-based device for holding in your hands while surfing the net and using the typical social apps.
The use-case of an attached keyboard and the fully fledged Office app suite is not what this device is primarly for.
I think I'm beginning to understand why there's so much excitement over the Surface. It's because the Windows world doesn't have Ultrabooks.
Or rather, up until recently with the Xenbook and the Carbon, all of the ultrabooks in the Windows world have been really really bad. But I don't think that the market has found the Xenbook and the Carbon yet. And maybe there's a general belief in the Windows world that you don't have to pay for quality - I think all of the Microsoft faithful here are hoping that Microsoft has given them a $500 Ultrabook, which of course they haven't.
