i've read neuromancer at least five times and i still feel like i never actually read it. it's a weirdly-written book with little environmental exposition - but i still love it.
There's something magical about a strongly consistent fictional world where all the characters understand the world and what's happening but the reader is baffled. It elevates the experience of visiting a strange new place to a new level of immersion.
And truth be told, I probably will read it again, although it might not be tomorrow. :-)
