For me, it was quite a good day, since the things i feared the most didn't materialize. Nothing major was open-sourced. In fact 'open-source' wasn't even mentioned on the keynote. Wheew. I was really scared that something (like .net) would somehow be opened.
That right there tells me that you don't really give a rat's a$$ about open source. You just want Microsoft to fail, and you somehow think that Microsoft will do so as long as they don't embrace open source (how misguided that notion might be).
Microsoft slowly but surly keeps on sailing in the same direction it started in the '90. Destination: irrelevancy, ETA: sooner and sooner with all the disruptions going on
