Interesting question. I suspect the answer could vary by dealer. I can say that if we had a brand new unit in a sealed box, we would not open the box. Some folks (I'd be one) prefer to be the first person to open the box, unwrap the plastic, etc.

Now in the case of the units that we do have that are "open box" and we offer as demo units - Yes, we have upgraded and will do so as long as we have the units "in stock."

I know that I have purchased other electronic gear in the past and the first thing that took place upon power-up (and network connection) was for the unit to "Call Home" and check for updates.
