I would be interested in seeing the numbers - how many were produced, expected to sell, and what the sales numbers have been.
Also, I'm new to the Android and Nexus game, so I don't have much perspective, but how is it this phone has been so much more popular when there have been previous Nexus devices. In fact, last years Galaxy Nexus was sold at the same price. Why is the demand higher for the N4, only 1 year later?
There seems to be a lot of buzz in tech circles, but the general public is largely unaware. Especially compared to the iPhone or SG3. Over the last 4 years or so, I've only seen two - a friend who had a G1 and Vz GN (that I just saw last weekend by chance in a liquor store)
I know it sounds silly but a relatively obscure phone like this has a certain "cool" factor, to me, even if others don't care or notice.
