I doubt a baseball is on the same level. It's not magical, it doesn't connect to everyone and everything you know, and everything you don't. A baseball is a mere sphere, out of context on a desk. A phone is something we check 60 times per day, which can vastly affect our emotions. A play sphere from a dying game surely doesn't elicit such a range of possibility as a modern marvel of addictive programming, something that needs to be buried in the bag to prevent distraction?
