I wholeheartedly agree. The last thing MS need is someone that thinks because they have one area of expertise, they automatically know everything else by some sort of osmosis. This is a career limiting trait in many IT guys and one which I have struggled to overcome in myself.
As for cynicism, it's all so depressing that you can rely upon nerdy keyboard warriors to continually knock everyone down and point out the bad, never allow themselves to see any good in anyone. It's corrosive and drags everyone around you down as well.
So: I hope Satya is good for Microsoft, he seems to be a smart guy, I like his cheeky smile, I hope that he is the sort of person who asks when he doesn't understand and sees the good in those around him.
