I also think that many people were expecting the 100 kwh battery upgrade that would push the highest range (100D) to over 300 miles. That 300 number is sort of like resistance - it's a magical number people want to see exceeded. I think there was disappointment with no mention of it in the refresh. I noticed that the Model S page has 294 miles of range for the 90D now. Seems like it was 293 before - so the new nose is simply cosmetic - no real value to aerodynamics.
I have SO many friends who say that when the range hits 350, they will be all over a Tesla. I'm not sure why that is such a magical number, but it seems the be the threshold for a lot of people. Of course, every few miles they add to range increases the number of people that would buy a Tesla. I for one like the 350 number also. I like being able to do long day trips without a thought of charging. And more importantly, I don't want to sit in a campground for 4 hours to get enough miles to make it back. Of course, 500 miles would be even better! But, we've got to break the 300 miles range first. The scary part is that we really haven't seen ANY range increases due to improvements in battery technology. We saw about 30 miles from AWD, and Tesla said battery technology would increase range by about 5% each year, but I'm still waiting to see that 15 miles get added out of the blue because the batteries suddenly got better.
