I think the keyboard will make a difference in how much you like it. As in, is this a good keyboard or not. I was in Walmart last night and they had some 10" keyboard/tablet case combinations on clearance and a pressed a few keys on one. It had better feel than they keyboard on my bloody Lenovo I'm typing on right now. If it's cramped or feels completely dead or whatever (like the 7" one you referred to earlier), then I'm sure you'll shy away from it.
Also, at 11.6", this thing is unwieldy. It's not of a convenient size to use one-handed, IMO, for any length of time. Maybe the weight will be low enough that it's not fatiguing to use for extended periods of time, but I'm not betting on it. So it keeps coming back to that keyboard.
That may make the difference, but I fully expect them to want at least two months of everyone using it 15 hours/week, and probably three months, as they'll have to test every update. It seems like a lot for people who only wanted a $60 tablet.
