Charlie Stross' Accelerando is available for free download and that's the version I read, on an open source ebook reader running on a lightly-hacked consumer electronic, no less, which felt very Strossian. At least, like the first few near-future chapters, until the run-away pace of technology (hence the book's title) took the characters and the plot far off into post-singularity weirdness.

Oh, man, I loved this book. It took me like two weeks to read it, just so I could wrap my head around all the technical stuff. But by the time I finished it my mind was thoroughly blown.
