Unless you plan to leave the UPC that comes with the car set up all the time, and travel without one, or plan to constantly pack it up and unpack it, you'd likely find yourself buying a second UPC anyway. In other words, there is a huge convenience benefit to having a second charger. Since the difference in cost between a second UPC and an HPWC is trivial (what is it now--$100?), I think it's pretty easy to rationalize away all of those costs, and really just look at the installation cost of the HPWC as the real determining factor.If you don't do it, and the Model S gets the 72A charging, how upset will you be? If you do install an HPWC, you'll be better set for anything Tesla sends our way.I say go for it!Edit: And as far as the likelihood of the Model S getting the 72 amp charger goes, since that was really what your question was, we do know that Tesla likes to streamline production, eliminating options whenever possible, etc. So based on that, I'd have to think eventually the 72 amp charger will make it to the Model S. When is anyone's guess.</blockquote>
