anecdotal-y: I've seen more Nokia smartphones in the northeast (Boston-NYC-Washington DC corridor which I travel through pretty often) post-windows switch than before. Maybe it's the marketing push from AT&T that has helped them sell more smartphone units now vs. in the past

The Nokia phones are more visible now, the industrial design is quite striking, but they are selling in far smaller numbers than ever.

Hold on, let me look up the sales numbers using my Palm Treo.
