Good story. I read it today in just about one sitting.
Coming on the heels of Snow Crash, I couldn't help but see some parellels. And I think it also reminded me of Lawnmower Man and Tron, though I have not seen either of those movies in years. Influences, not robberies.
The basic plot: Nick gets a new gadget that helps him navigate in his corporation's server. It consumes him, but also sets him free.
