1) Have to do a better job with the presentation. Didn't have any issues with viewing on Safari, but why did it start 5 minutes late - maybe it's ustream's latency? Also, almost seemed like they winged it with not enough scripting. How hard is it to choreograph this 20 minute presentation and script every second of it especially given the enormity of the presentation? I love Elon and everything he is trying to do, but I don't think Steve Jobs would have approved of the presentation.
3) Making charges free - big mistake. I may not speak for everyone, but given the price of the car, I'd wouldn't mind paying for the charge (even if it was the same amount as a full tank of gas) especially if it means that there will be more supercharging stations available. Imagine if tesla offered any existing gas station/highway rest stops the ability to put these in at no cost and it would be subsidized by customers who use it. Remember only about 2% of your charges can be supercharger charges, so the real usefulness of the supercharger are when you want to go on an out of town trip. I'd gladly trade off free charging for pay charging if it meant more charging stations would be available. Even if it meant the electricity were straight off the grid without the solar, still the CO2 released would still be less than an ICE car. Isn't that the rational that we are all using when we are charging at home?
