Emphatically agree.

Disagree. Always use the smallest model you can get away with, but if
the program won't work under a small model don't play games with
NEAR and FAR pointers... just go to a larger model. You will thank
yourself later when you get a real computer.

The massive performance advantage of small model over large is a
strong reason... so long as you don't have to use kludges to fit
into small model.

After all, all of UNIX ran in small model once upon a time :->.
