Wow, I go out for the few hours the market is open, and look what happens. Well, I did say "if."
Batteries: I have a high degree of confidence in them. But we need to realize that there is insufficient real-world experience to make absolute statements, and the car-buying public will need time, and will need to see how the batteries do over a period of years. The Toyota Prius, which had six or seven years on the road before the 2004 model went on the market, still took several years more to become mainstream, and that was with a long-established battery chemistry. The stock market will watch sales, and sales will rise gradually as the public gains confidence.
I am a Tesla customer, but I have declared my house an "Apple Free Zone". I went so far as to set up my WiFi router to not allow connections from Apple branded devices. If Apple were to buy Tesla, I might have to start looking at other cars (Let's just hope this does not happen, because I REALLY want a Model S)
Wow, that is a level of hate I don't often see outside of discussions on politics or religion. I hate Microsoft, and I won't allow MS software on my computer or buy a device that runs MS software. But setting up a router to reject Apple-branded devices sounds extreme to me. Are you concerned that an Apple device will cause harm to your network, or do you just hate Apple so much that you reject people who own their devices?
I like Apple, mainly because OS X is Unix. And my first iPod was so much better than my first MP3 player. I had trouble with my Airport router, but I've been happy with my iMac, Airport Express (for travel), and iPod, and 3 out of 4 seems pretty good to me. And of course I love my Roadster.
