Powershell made me actually switch to Windows. I was playing with WSL when it came out and learn of Powershell. WSL has some warts but Powershell means I cannot use Linux anymore :(
I'm hoping Powershell on Linux will soon be at par with the Windows counterpart (right now it's pretty buggy)
Indeed, PowerShell is onto something. Such delight it is to work with. Especially when you start to build your own tools for it.
