It's really great for that to be honest: I don't have to worry about the games once I upload them (unless I decide to update them or make changes). I also run a site with music games for teachers that's subscription based and that takes up more mental bandwidth from day to day than the apps since I'm always trying to improve it to help keep customers subscribed. If you head into the App store with modest expectations, I think it can become a decent source of income. I talk to relatives and friends and they seem to think that having an app in the store means you'll get millions of downloads a month, but I think that skewed perception is created by the focus on the really big apps in the store (that seem to get a lot of help directly from Apple in how prominently they're placed in the store).
