I assume details of these can be found in an appropriate text. >Can't I do that in Mathematica, too? Clearly you can since MathStatica is simply a Mathematica package.

This should not be necessary. For example, my init file loads Graphics`Graphics` and Utilites`CleanSlate` at startup. MathStatica loads just fine after this. Nor does MathStatica oject to being loaded after some packages in a session. MathStatic does object if assignments have been before it is loaded, i.e., In[1]:= <<EnhancedDataManipulation`; In[2]:= <<MathStatica`; generates no errors but In[1]:= <<EnhancedDataManipulation`; In[2]:= m=2; In[3]:= <<mathstatica`; reults in MathStatica complaining about not being loaded from a brand new fresh kernel >Once I get into it and start dealing with the quirky interface, the >unnecessary splash screen and web-site palette, etc. --- it just never >seems worthwhile. I agree the splash screen is unnecessary as well as the header MathStatica inserts into the notebook. I also find it annoying to not be able to load MathStatica whenever I like. But it isn't quite as bad as you suggest here. Ultimately, whether you consider MathStatica worthwhile or not will depend on your needs and tolerance to the way MathStatica operates,
