Financially savvy people are much more likely to have a desktop, I would think.

Mu mother-in-law does not have a laptop or desktop. She barely uses her iPad. If it’s not on the phone, it might as well not exist. My father-in-law has a PC at work and a Mac laptop, but he uses them only for work - his casual internet use is entirely on the phone. My wife uses multiple iPads and her phone, but only uses a desktop at work or when working at home.

Most people I know don’t actually own personal computers other than their phone or tablet.
