Coders at Work by Peter Siebel and Founders at Work by Jessica Livingston - I loved reading about the founder's stories and first-hand perspectives of notable programmers.
The Pleasures and Sorrows of Work by Alain de Botton - really interesting perspective on "work" and various types of careers and people that find happiness in them/work itself.
Superfreakonomics by Steven Levitt and Stephen Dubner - even if you don't agree with their arguments or think that the authors are all fluff, I think that their writing style is exceptionally clear and easy to understand.
The Black Swan by Nassim Nicholas Taleb - some really interesting ideas and analysis, although the book could have been 1/2 as short
Fiction:
Anathem by Neal Stephenson - starts out slow but after the first 200 pages it became a really great story that I couldn't put down.
Life of Pi by Yann Martel - loved the main story of the book, the controversial ending didn't bother me too much because I don't feel like it takes away from the story at all.
The Girl With The Dragon Tattoo and The Girl Who Played With Fire by Stieg Larsson - cheap fun and suspenseful
The Road by Cormac McCarthy - I don't think much needs to be said about this book
White Tiger by Aravind Adiga - extremely interesting and gripping novel about a side of the world most of us Westerners never see
Hitchhikers Guide to the Galaxy by Douglas Adams - finally read this classic. I read the "Ultimate Edition" which contains all 5 of Adams' novel, loved the first one but the story felt like it started to putter out by the third.
