Subject: normal table use in elementary statistics?

I have been teaching statistics for years using the normal table. I use the
one that Moore does with the areas cumulative from the left. Many of my
students now have TI-83s. These TI-83s can give table areas (cumualative
from the left) or z values from left areas. They can even figure out
scores (like IQs or women's heights) using the TI-83 normal feature.
Do you think I should still teach them how to use the normal table to do
the problems or is this approach too old fashioned? If they use a TI-83 I
guess I worry that they won't really understand what is going on and they
will have trouble later in the course when things become more complicated.
What do you think?
1. Use only the table and formula for z
2. Use only the TI-83 approach.
3. Use both.
If you pick number 3, which do you think should be taught first? On which
method should emphasis be placed?
