There is no mingw64 package of openssh and putty is "made for Windows",
which means that everything works out of the box (I'm not talking about
Tramp, which I don't use.)

I also use find quite often while using a shell. For Emacs, ag (the
silver searcher) makes rgrep & co. irrelevant and my Dired usage is
quite basic.

If there is no ls available, Emacs uses its own facilities. That applies
to Eshell, Dired, etc.

No, not difficult, just slow.

Launching processes is slower in Windows than in GNU/Linux, plus Git is
heavily optimized for GNU/Linux, plus (and this is not really a "plus"
but a "times") Magit does a lot of git calls, about 50 runs of git
whenever the status buffer is updated, last time I checked.

You're welcome.
