I'm interested in reactions from ONLY those who have had first hand experience with the Beta vehicle (in person). Here's my story, and a related one, that sort of explains my reason for asking:
As I'd mentioned in another post I had been excited about this car for some time. However, what I may not have mentioned was that I was somewhat on the fence. That was until a good friend, and reservation holder, invited me to go with him to the Model S beta event at the factory in October. This journey is what made up my mind that I absolutely had to have this car. Shortly after they showed the car at a local Tesla dealer, and I took my wife and daughter, and they were equally excited about it as I was. So this is where it gets interesting...
The reservation holder I went with was not as impressed as I was. He rode in the rear seat, and I was in the front passenger. He commented that the fit and finish was not up to par, and that this car would never be competitive against BMW (he's a rather big fan). I explained that this was a Beta vehicle, not a production car, and was going to be a bit rough. This didn't sway him. In fact in a later conversation his wife mentioned seeing the car at the dealer and had the same unimpressed feeling her husband did, and proceeded to try to talk me into a BMW (not interested, thank you).
My concern is this. For people outside of any industry where they might have first hand experience with "beta" products, what they are, and what they can look like compared to the final production release, this may be confusing for some.
