Nielsen: State of the Media: Consumer Usage Report 2011
Some interesting numbers:
Apparently Americans of Asian ethnicity are the only group which statistically have iPhones more than Android based devices. Smart phones are still less than half (43%) of the American cell phone market.
Only 5.7% of broadband users only have broadcast television (don't subscribe to satellite or cable television). Surprisingly 30 Million Americans watch television on their cell phones. I always assumed that was simply something that was advertised as a feature but no one actually did.
There are a whole lot more interesting numbers in the report, so go check out how the world's changing.
