If you're looking for command-parity with Unix commands, why not just install Cygwin?

If you'll pardon the minor thread jack, though, since you bring up Cmd.exe, does anyone know a decent console/shell program on Windows (where decent is defined by one that has tabbed shells, and, preferably, mouse copy-paste semantics akin to Linux?) I've found Console, but it has some... annoying idiosyncrasies.
