Neuromancer

It is rare for an entire book to be written from the perspective of a criminal but this one does just that. There were several ideas that were very interesting and the criminal viewpoint allowed the author to show more of the potential than a different perspective would have allowed. This is most evident in the ideas of drugs, hacking, and Riviera's holographic projections. The drug use is very casual for Case seemingly because of his criminal existence which in turn makes the drugs easily accessible. As a criminal he is most upset when his ability to use drugs is taken away which he eventually circumvents and finally restores at the end of the book. Almost everything that occurs in cyberspace during the book has criminal purposes considering that respectable programmers or cyberspace users would not view ICE or programs in the way Case and The Construct do. Riviera's holographic projection is versatile and demonstrates both legitimate and criminal uses because he uses it primarily for nefarious purposes, but it is also used as entertainment at one point. If Riviera had not been a criminal it is unlikely that his abilities of scaring people with scorpions, protecting himself with false images, or blinding people would have been demonstrated.

Personally I would have a tough choice deciding between Molly's claw/combat upgrades and Riviera's holographic projections if I could choose one myself. Solution: get both technologies and formulate ways of using them to compliment each other.
