I agree the keychains are probably fairly far over the line. The cockroach backpack is not something I'd consider appropriate for young children, but for teenagers/etc., it seems like a pretty reasonable thing. If it exposed an API and did two way communication/logging it would be a lot more interesting. Maybe in both cases (keychain and current-backpack), it's primarily the uselessness of it which is most objectionable.
