I think everyone arguing over case sensitivity is missing something.
Why treat letters specially?  For example, UNIX treats a and A
differently just as it treats = and % differently.  I see no reason to
restrict filenames to [a-zA-Z0-9] and a few special characters like .
and -; and given that uniformity case folding makes as much (or as
little) sense as folding 0123456789 onto !"#$%&'()* (to pick a
particularly silly example).

I would say that (1) is not particularly useful, but it can be nice to
be able to create files named D.mcgill-X04T2 and D.mcgill-X04t2 in the
same directory.  This is less of an issue, though; it's just as easy to
make a program use base-36 as base-62 or base-126.
