Hello out there in netland!

I am sort of a newcomer to APL.  My father has used it ever since he got
his first non - punchcard account, but I know little about it other than
the following:
APL has a strange keymap
It is based on preforming operations on matricies

Here's my questions.  I suspect that many other non APL's are listening in
on this group, so the answers will be of help to many.
What differences (other than speed and documenttion, as mentioned in the
guide to low cost apl's a while back) are there between saplpc and the
inversion version.  I am interested in whether or not the extra expense is
worth it.  Also, other than the fact that the keyboard is not goofey (at
least to a new apl user) what are the advantages / disadvantages of J as
opposed to apl.
The applications I forsee using apl for are physics lab computations
(which I currently complete on a spreadsheet - yuck) and integration of
ugly intigrals using brute force.

Thanks for your help.
Andy
