During Google's Q4 2014 earnings call this afternoon, the company's Chief Financial Officer Patrick Pichette spoke about the many ups and downs of the past three months. In explaining the downs of this past quarter, Pichette spoke of two points in particular. One was the Exchange Rate between the United States and international consumers. The other reason Pichette gave for Google not hitting goals they'd set for themselves was the less-than-stellar supply they had with the Nexus 6. Pichette also mentioned Google Glass, as it were, as an example of what Google does when a project doesn't work.
