I don't think a Bratz Doll on a Keychain in the store is useful, but my 5 year old niece will get a solid week of entertainment out of it. Sure that is useful, but do we want to compare it to a SawStop or iPhone? All of them are useful, but to different degrees, different people, and across varying lifespans. You can argue that anything is useful if it is "used", but let's not pretend there isn't a spectrum here.
