That is not an assumption or a guess. I've deployed Wi-Fi to farms and the first thing they reach for is an iPad and Netflix.
Despite his age he was a really early ebook adopter since they live in such a rural spot. The library can transfer books from bigger cities, but the shipping time is so slow and there is a limit to the number of books you can check out at once. Basically the netflix disc problem before they switched to streaming. Taking out ebooks from the library is really easy and a great way to pass the dull time spent on the tractor.
Some of the more sophisticated tractors are like being in a plane on auto-pilot. Some you can even pilot remotely if you're really not in the mood to drive it, like a gigantic Roomba.
Legal fears scare tractor manufacturers from making something truly autonomous; there's supposed to be a human in the driver's seat at all times. That said, John Deere has had self-driving tractors for almost 20 years, now. And I mean they automatically steer themselves, they don't just go straight for a predetermined amount of time (though they can do that, too.)
