Hasn't the Oyua shown that most Android apps are pretty terrible if not used on a touchscreen device? For the features you want, it's going to be comparably priced to a $1000 Surface Pro.
It's debatable whether it's shown that, but it doesn't give us much information about this device even if that's true. The statement that Android apps are terrible on non-touchscreens doesn't necessarily tell us anything about how good they are on touch-capable devices.
The big failures exist in the 3rd-party apps and the home-screen. With a custom home-screen and a secondary app-store full of key/mouse-friendly apps? You could make a comfy Android/Netbook experience.
I think the Oyua has really shown also that games work well with a controller. Many android games are just trying to use the screen to emulate what we're used to (buttons, d-pad, analog sticks, etc)
