Basically am a math physics geek who dreams up weird optics for a
living whenever I am s'posed to be doing other things. A lot of this
is pencil and paper but ya know, spread sheets are nice. I got no
probs pokin round in the innards of a computer but have learned to
hate the seeming arbitrariness of software. I could still program in
Fortran if needed but Vis Basic is nice. I really wouldnt use it for
movies and would only send e-mail to family which is redundant with a
cell phone so the only reason for having it is for when I get bored
and wanna poke around at some problem.

So why are you wasting our time by asking if you should have one?
Either do it or don't, it really doesn't matter. You haven't given any
reason to have it other than maybe it would be nice if you dreamed up
something to use it for. So why are you asking us?
