Google’s Nexus 4 has been on sale for three months, although one could argue that it has been on sale for a couple of weeks, since it wasn’t really available anywhere. For some reason, Google grossly underestimated demand for its latest vanilla Android phone, resulting in ridiculous shortages in every single market.
Android enthusiasts managed to work out that Google shipped just a million units in the first three months of sales, after four months in production.
