Gift cards that give in other ways

Target seems to be offering odd little gift cards (WOW Cards) this holiday season, that do everything from play music and flash lights, to turn into USB drives and (get this) digital cameras. The digital camera one even comes with 40 free prints and boasts 1.2 MPx quality. So instead of using the card and throwing it away, I guess you can keep taking pictures with it? There's really no info on the target website other than a short video, so I'm not sure if you can replace the battery and use it over and over. One would hope, if the idea is to keep garbage out of the landfills.
