You don't mean that the GP (taliesinb) is confused, do you?. He works for Wolfram Research, developing Mathematica.

That is what I meant, but I guess I look like the fool now. I still don't see that Mathematica 10 has been released, but I guess it is close.

It hasn't been released, but you can effectively get it on a Raspberry Pi: http://wolfram.com/raspi

I'm going to go out on a limb and guess that v. 10 has not yet been released but is in common use internally at Wolfram.
