Yuch. Why put a slide out keyboard on it. That makes it a netbook with a lousy keyboard, not a tablet. Granted, I don't think anyone makes a convertible netbook, but if you need a keyboard, buy a BT one for your tablet, if you need a tablet. That way the tablet can be thinner, and you get a decent keyboard.
Why do people think adding a finger friendly UI to Windows is the answer? I don't think Win 7 is that disastrous for touch use, but if you do, all you wind up is a finger friendly way to launch non-friendly apps. The apps themselves need to change, not the OS. Touch capable windows based machines haven't made a great market impact, so developing apps supporting touch hasn't been terribly lucrative I would guess. Mobile OS apps are a different story as a touch screen is pretty much assumed these days. Adding a touch GUI to Windows is like adding HTC Sense to WM6. Great until you drop into an actual application. Fix the apps.
