I am only recently an iPad owner. I still use my Mac (a Mini, not a MacBook, but I voted anyway) much more often for internet activities. The computer is upstairs, and the iPad stays downstairs. I'll use the iPad to look something up while watching TV if something I'm watching triggers a question. Before the iPad, I'd think that I wanted to check something out later rather than interrupting whatever I was watching on TV. But then, of course, I would forget what it was that I wanted to know.
I also use the Mac to live stream worship from our church through the AppleTV, even though I could use the iPad. Using the TV allows my wife and I to sit in our usual spots for viewing. And I use the Mac for Zoom and Skype, even though the iPad can do those as well.
I think the iPad has a sharper image than the 15 year old TV and the 6 year old computer monitor, and the relative scale of the iPad image, being viewed from arm's length is comparable to sitting across the room from the TV, so I guess it's just that habits are ingrained.
