The N800's success actually took some inside Nokia by surprise (I was not one of them). The infrastructure wasn't quite ready for the sales numbers. And at some point in almost any new product's lifecycle, there's that question: is it successful enough to continue, or do we let it die (ie, N-Gage device) and take the hit? The platform was actually on a bubble for a while-- too successful to kill, not successful enough to build a business around.
