Setting up a computer for a toddler

I'm not sure how many people do this or will actually be interested in setting up a Windows 8 computer for children, but, I will document the process as we go.  It has been our tradition that, for our grand kids 2nd birthday, we get them each a computer.  On October 6th, our 8th grand child. Travis, will celebrate his 2nd birthday.  So, computer or tablet?
We have decided on a Windows 8 touch screen desktop computer.  We'll need one that is pretty sturdy because Travis is a pretty active child.
He will need to have an internet presence and because he is so young, he will need to be well protected.
Follow the Blog over the next couple of weeks to see what we choose, how we set it up and the applications we choose.
