William Gibson wrote Neuromancer, and it had an incredible cultural impact. But everything else he wrote hasn't come close. I've read the Bigend trilogy. Can't really remember anything that happened in those books.
On the other hand, Cory Doctorow is the writer I wish I was. He does high tech thrillers the way they're supposed to be. Attack Surface is excellent, a master class in a flawed but sympathetic main character. Just read Red Team Blues. Doctorow reveals how interesting forensic accounting really is.
Do yourself a favor and read Walkaway. My favorite book. The structure is a bit of a departure from Doctorow's other books. More like Kim Stanley Robinson in that there is a group of characters but the real main character is the birth of a post scarcity society.
