The New York metro area has the highest per capita ownership of emerging technologies (iPads, netbooks, smartphones, and Blu-ray players) in the US, whereas the Phoenix metro area has the highest ownership of older gadgets, such as VCRs and CRT (cathode ray tube) TVs, according to a survey from Retrevo.

The San Francisco Bay Area boasts the highest ownership of green technologies—such as recycled electronics devices and energy-efficient flat panel TVs—and the lowest per-capita levels of power-hungry CRT TVs. Bay Area residents are also most likely to stream media (e.g., music, TV shows, and movies) via the Web.

Greater Atlanta ranks highest in TV ownership, with households in that region reporting more TVs in more places in their homes, such as in bathrooms and garages. Atlanta metro residents also record the most TV shows and watch more TV than residents of other regions.
