a "token of appreciation", even if tweeted, should not be expected, but just that, a token of appreciation. I think a lot of people are setting themselves up for disappointment expecting something quite grand. Is everyone going to start ranting when a mailed postcard as your token shows up vs something with a monetary value? Or if it is something of significantly less value than expected, like a key chain or sticker (apple style)?
Personally, when I reserved, the only thing I expected to get from it was the ability to give Tesla another $40k +/- in two years +/-.
