Many people are put off by Powershell because they believe that 20 years of experience in bash or CMD will allow them just fire up Powershell and get by. You will not get by. There's a good amount of gotchas and you will get stuck on some unexpected behavior within minutes.

The thing is, if you want to use Powershell you do need to spend a few days just learning Powershell and nothing else. I have the impression some people don't want to do the effort. It's a pity because it truly is vastly better than any other shell in existence.
