Changed: the ease of switching when restlessness kicks in. I have the Kindle app on my phone with several partially-read books in it. I can also pull up a browser tab at any moment. It takes some degree of effort to stay on-task in a single book, and it's probably analogous to meditation.
With digital pursuits it's easy to fall into FOMO anxiety cycles. The classic "stuck on the Netflix menu" conundrum. When you pay attention to it, you realize you're just kind of trying to minmax the ratio of enjoyment to boredom in one's escapism, which can't be a healthy way to treat leisure.
Same: escapism.
