What to do with a broken SGS3

My wife and I both have Google Nexus 5 phones (maybe I’ll write more about that decision later) and couldn’t be happier.  However, prior to our current setup, we had a Samsung Galaxy S3 (SGS3) we passed around for a while until the screen broke:

Beyond the screen having cracks in it, everything works perfectly fine (even the touch sensing bits).  So, the question now is, what do I do with this hardware?  The current ideas floating around my head are:

  1. Setup a Kodi (formerly XBMC) server, replacing my current full sized tower chassis that is in the living room
  2. Make it a little more safe and give it to my daughter going into kindergarten in a locked down mode so I can keep tabs on her
  3. Set it up as a workstation for my children to play with
  4. Somehow tie it into my pimometer project

Anyone else have any great ideas?
