I have a dell duo - hybrid notebook/ tablet with a swivel screen.
It's is a hit chunky for use as a tablet, and the viewing angles are atrocious compared to my touchpad. This means it is usually more comfortable to use it as a notebook. It is axfun bit of kit though, and it feels very comfortable to use the touchscreen whilst the screen is vertical. In terms of processor and ram, it is a bit sluggish. W7 really is not designed well for touch, and can be fiddley to navigate via small buttons. I am sure w8 will be great on the duo. I intend to test the developer build shortly.
