Even-though I'm not huge Windows fan, I like to watch Scott Hanselman's videos. He's smart and funny, but hope he's wrong with "The year of Linux on the (Windows)". Not sure what is the Microsoft's initiative with WSL, but if I were them, I would be very careful. WSL can be two sided sword for them. I think for most Linux users, WSL is not enough to switch to Windows (there will be some, but talking about majority here). So IMO WSL will attract Windows user to Linux and not the other way round. Those same users may later discover that, they're actually more productive in Linux and eventually migrate away from Windows. Microsoft is also giving good reasons to do so (telemetry, forced updates,...). Almost hear Satya Nadella singing Ariana Grande's – No Tears Left To Cry :D
