Yup, all this means is how the businesses define the market segment they are in. If consumers were to define their own segment, there will be no end to this debate.

So to have a comparison, we should check with Nokia what the N800's target segment is, and we compare with what Sharp's target segment is for their device. If the segements are the same, then based on the above, we should have a non-emotional debate. If there is overlap of segments, then we can only look at the overlap portion to discuss. If your own personal needs are outside of the overlapped portion, then really, you are the best judge as to what is best for you.
