Jacqui Cheng, ars technica:
According to Pew, 28 percent of smartphone owners access the Internet this way most of the time, which amounts to 10 percent of all cell owners or 8 percent of all adults in the US. Mobile-only access to the Internet is nothing new in other parts of the world, but the growing availability of smartphones and the continued difficulty of getting broadband access in low-income or rural areas is undoubtedly feeding this trend in the US.
There are even more interesting tidbits in the study as reported. This probably speaks to heightened laziness on our society’s part as well.
Also: From Sarah Kessler, Mashable, on the same report:
More Americans own Smartphones than hold a bachelor’s degree or speak another language in their homes, according to a Pew Internet Project report released Monday.
