I agree he isn't that good at delivery but he feels very authentic and that does it for me more than the total fakery I see at e.g. Apple now. I say this because I am a big Apple fan I liked Steve Jobs presentations, but it hurts my ears when everybody at Apple try to sound like Steve Jobs throwing out "Best ever", "Only Apple can do this", "This is the best X we ever built" etc.

Elon Musk never says rubbish like this which feels totally markety. When Elon Musk rants about something it feels more like a geek who is really excited about something, rather than slick market speak.
