Yes, I said - most people work from a desktop or a laptop. BUT, they also have their devices where they access other stuff while at work. So they are using maybe 2-5 in addition to their computer imvho. The devices are almost always available because they're mobile. Laptop less so obviously but still portable.
I mean, I know a lot of people that check their smart watch, iPad and/or phone throughout the day while working.
For example, if my husband used iHub (which he doesn't) as a resource to trade stocks, during the trading day he may check his portfolio or prices through iHub. He certainly wouldn't access it on his computer. He would access it on one of his devices. I know people that use a device when they're walking on a treadmill.
The generalizations that people with real money aren't using their devices to access plenty of websites all the time just doesn't jive with my real world experiences. Yes, I assume everyone I know has a computer. And I'd say that the vast majority of every one I know has an average of 3-5 devices they use pretty regularly.
