Great! Not everyone has that! I do but if I could only implement one type of 2FA I'd probably still pick SMS.

Smart phones are obviously phones and have biometrics. What you're left with is comparing the number of people with non-smart phones (~31 million in the U.S.) to the number of people without smartphones but who have biometric tablets, Windows Hello-enabled computers, PIV cards, etc.
In my social circle, the people who don't have smart phones are:
- People with disabilities that make reading from a small screen or texting a lot impractical.
- People who work in harsh environments who want something more rugged than a device made out of glass.
- People wary of the distraction of carrying around an entertainment device.
All of these people except one also have an iPad (especially the first group, as the larger screens help a lot). The one who doesn't does have a Dell XPS 13.
I would also wager the number of people with dumb phones are close (but not as close) to those having computers without any biometric capabilities (and if they have them, they’re not set up).
