I don't want to have to relearn everything like I do for powershell, everything from *nix should carry over. I want a package manager for everything, something like nuget (which is great), but for the entire OS like brew/apt/yum. I want a ssh client/alternative, I should be able to administer a windows box without having to RDP in. These are my main issues but i'm sure there are plenty of other small ones. My workflow is typically web development but I work for a smallish company and do a bit of Ops as well.
