Win8を触ってたらPowerShellというのをみつけたのでちょっと触ってみましたが、結論から言えば全然代替にはならない感じで残念でした(cmd.exeが便利でという意味ではありません)
Aliasがコマンドに結構貼られていて、お！と一瞬思ったんですが、やっぱりそうでもなかったです。

そもそもですね、そもそもですね、ドラッグした時の文字列コピーがどうしてああいう選択範囲になるのかっていう話と、仕方がないのだけどディレクトリを/できるのかできるのかっていうのは、もうどうしたってどうしたってしょうがないのですね。
というわけで、今はnyaos + console2 + cygwinを検討中です。
