Yes, I agree, although you can use org-time-stamp everywhere (in emacs).
And you can actually insert timestamps simply by writing

  <2011-10-13 >

with the whitespace to make it a valid timestamp.  That will be shown as
day entry in the agenda, and you might have typed it in using some
non-emacs text editor on you phone.

Now, back in org-mode, simply S-<up> and S-<down> on any number, and et
voila, the missing day name abbrev is added automatically.

No, I don't think so.  Manipulating and creating timestamps using the
provided commands ensures their correctness, but for actual calculation
the day names are ignored.  It's just for humans.
