Maybe I am in a bubble, but in my family I was the only Apple user 5 years ago. Today we have got not a single Windows device left anymore. My wife has a MBA now, my mum has a MBA now, my sister has a MBA now.
Same goes for the .NET community. So many developers who some time ago would have only developed on a Windows machine all switched to Apple over the last few years and most people don't ever look back.
I appreciate that those personal anecdotes don't mean anything, but let's put it this way, I was not surprised to see a 30% drop in Windows sells in Microsoft's last financial statement.
