My favorite examples are from several years ago -- Charles Stross's Halting State and Vernor Vinge's Rainbows End. The technology portrayed probably doesn't seem quite as amazing today in 2013, but I'm always reminded of how technology seems to be converging on those futures whenever I read over the latest APIs from the Khronos Group. More recently, Ramez Naam's _Nexus_ from earlier this year is pretty awesome, although a little more out there than the other two.
