I agree with all of those, emphatically with numbers 1,2,3,6,7,9 and 10. I'd also add Stranger in a Strange Land, purely because of it's departure from more 'mainstream' (Using that word very lightly here) sci-fi. There will never be a Stranger in a Strange Land adaptation. Also Jurassic Park needs to be on any list of sci-fi essentials.
You know, The Jurassic Park movie was so good, I always forget about the book, which was the original reason I became interested. I never think of this when thinking about sci-fi and it is a perfect pick.
The thing that I like about it is that it perfectly captures this wild-wild west feeling in biotech during the 80's and 90's. I think our expectations of genetic engineering and different kinds of 'consumer biologicals' are far more realistic now, and we've lost a lot of the wonder associated with this kind of science.
Neuromancer was Windup Girl 30 years ago. The cultural aspects of it, with a heapin' helpin' of Cold War Paranoia, are the basis of Islands in the Net by Bruce Sterling (also 30 years old). That's why I recommended Windup Girl - it's one of the few books out there that isn't older than everybody reading this.
