I've heard that GenX/Millenials are in a sort of PC goldilocks zone. People older than that cohort don't know computers and therefore use phones for everything, people younger don't know computers and also use phones for everything.

I'm a tech loving boomer, I always use my PC for banking, ordering, etc. My wife, however, almost always uses her cell, which is great for when we are traveling. Even though we're only five years apart in age, she's lite years ahead of me with a cell. I freely admit part of my reluctance for using my cell is the mobile tracking ability of companies.
