No thanks! It looks like a novel design and very cool, but there are a number of points that make a Tablet more attractive to me. Some points against it in my eyes:

1) ATOM processor. While the Atom easily beats the Hummingbird/Tegra2/whatever, it doesn't have that ultra-low power standby mode. Meaning, that your device is either sleeping or awake. I like the always online capabilities of ARM SoCs and instant on functionality.
2) Win7 -- of course this can be swapped for another os, but my complaint is that it's not designed for a touch screen.
3) Battery life. Again related to the Atom CPU.

I'd rather get a Galaxy Tab and a 13" Asus UL30Vt, than this device alone. Why the UL30VT? 10 hours of battery life real-world, OC'd C2D SU7300 CPU, GeForce 210m GPU, thin, light, beautiful, ~$700. A perfect work companion for tasks that are not too demanding.

Don't get me wrong, the duo is a very sleek device that oozes 'potential', but in practice I have serious doubts that it will be as good a tablet and being an Atom and using a desktop OS and I know that it will be a subpar notebook as well (from experience).

Of course, I enjoy being proven wrong, so please let us know how it goes!
