Perhaps you should try it and then make a pronouncement!
My bad, but I only have access to Cygwin and I tried `xargs ls' ...
anyways this seems interesting, will check at work tomorrow.
This is interesting.

The issue does seem to be, as Kapil Paranjape pointed out,
that vi has it's stdin set to /dev/null which it doesn't like.
http://sial.org/howto/shell/ suggests that you can use
backticks (instead of xargs) like so:
$ vi `find -name "*.h"`
Or, just use emacs.
