Counter-suggestion:

Dive totally into the Windows world.

My background was star-nix, and when i found myself having to use Windows, I always did something like Cygwin, gvim, etc. Which worked fine.

But it necessarily limited my expertise in Windows. Being an expert in Windows, while working in a Windows environment, should make you a more valuable player.

When someone asks you how you do something, you don't want their eyes to glaze over when you say "First you have to install Cygwin." You make yourself a useless resource in their opinion.

Everything that can be done as a user in *nix can be done in Windows, in some Windows way. Be useful to yourself and your colleagues.

I think.

This. With the addition of diving into Powershell. It is quite different than *NIX shells. It is the fabric of Windows in the enterprise and cloud.
