Why not just buy a netbook, and mod the touchscreen kit onto it? Won't that be easier? Also better, because it has more horsepower and software? Not to mention some of the new ones have 3G built in?

I mean, it you are going through all the trouble to somehow connect a different LCD to the N800, and a USB touchscreen (which would require a powered hub and drivers), you can obviously mod a netbook to do the same...
