I got it for Christmas, so just last month actually! I think it's possible it's just too late now, apart from a historical perspective. The concepts have become obvious and the prose is... not for me.

In terms of influence I suppose I'm mostly thinking of movies and shows such as the Matrix, but I also read so many short stories involving VR and techno-dystopias it's hard to pinpoint. Snowcrash is certainly up there (yes I tried to read Snowcrash first, having done no research, and liked it even less). Having played every Shadowrun game doesn't help (the universe is in a lot of ways "just" fantasy Neuromancer).

All that being said, Neuromancer doesn't read like a cheap copy either. More like I've been riding bicycles all my life and someone presented me with a penny farthing. I appreciate the innovation, it's just not particularly mind-blowing anymore.
