The points nate@hobbes.intel.com makes are valid.  The timings most likely do
not the time used by subprocesses (and definitely not programs run during a
temporary suspension) by the two editors, do they?  (Please correct me post
haste if I'm mistaken, so I can start talking out of a different side of my
mouth!).  GNU Emacs is a totally different animal than vi.  It is an order of
magnitude more functional, and performs a lot more intelligently than it's
usually given credit for.  I wouldn't be surprised to find that a significant
portion of time is spent making frequent checkpoints and backups.  I wouldn't
be surprised to find that a significant portion of time is spent justifying
text, which would have to otherwise be done by another process.  Etc.  I wonder
if it's even possible to write a decent interface to another process in vi.
Now, if you get all that extra functionality at a mere 4 times the cost, even
10 time the cost, you've got a tremendous bargain.
