Poll: What is the biggest development surprise of 2011?

Developers, do you think the biggest surprise of the year is the Windows 8 Developer Preview, HTML5's rise to prominence, or something else? Take the poll.

2011 had some pretty big surprises for developers, much more so than the last few years. In my mind, the Windows 8 Developer Preview was a complete bombshell for developers and announced Microsoft's intention to slowly shift away from the desktop paradigm completely. Adobe cancelled mobile Flash, which made a lot of sense, but plenty of folks didn't see it coming. Likewise for Microsoft telling folks that HTML5 was good enough for Web needs and relegating Silverlight to a number of niches. And the unfinished, still stabilizing HTML5 has suddenly become a platform of choice for many developers. Developers, let us know what you surprised you the most this year.
