(CNN) -- If you're a tech news junkie (and that's why you're reading CNN.com Tech, right?), you might have gotten the impression that everyone already has -- or at least wants -- a smartphone. Or that smartphones and tablets are the only mobile devices that matter.
But new research from Forrester indicates that while cell phone penetration is high across all U.S. demographics (82 percent of consumers own a cell phone, and 73 percent report that cell phones are their "most used device"), only 17 percent of Americans own a smartphone.
This is true even among the most digitally savvy generations: Gen X (roughly ages 31-40) and Gen Y (roughly ages 18-30).
According to Forrester, Gen Yers and Gen Xers are most likely to own smartphones. However, less than one-fourth of cell phone users in both of those age groups own a smartphone.
Also, Forrester reports that less than one-fourth of U.S. mobile phone owners have an unlimited data plan.
All of which means that the vast majority (more than 75 percent) of the "digital native" generations does not use smartphones. Instead, they rely on cheaper, simpler-feature phones and limited access to mobile data-supported services. Read further.
