[....he can imagine some Pokemon being pissed off about being crammed inside a computer, but fortunately none of Banjou's have a bad attitude about things like that.]

You know, there probably is. It's not like all of my Pokemon have the exact same personality. If you have one that's quicker to anger, it's less likely to enjoy being in a computer for a while, even if it doesn't actually get sick or hungry while stored.
