I haven't used Powershell at all. Would've been far better for MSFT to have adopted bash and provided windows-specific utilities where absolutely necessary.

DOS / cmd.exe, last I checked, didn't have true pipes, true shell expansion, or true readline capabilities (unless it's now GPLd, which I very much doubt). It does have some history and tab completion (though that last works weirdly IMO).

By shell expansion: expansion of wildcard globs by the shell, and not by specific utilities. Piping -- I forget the specifics, but it's always seemed hit or miss, mostly miss. Readline: see readline(3).
