Klink:
Actually, research has always been my main goal. I have always had a ton of questions that I wanted to try and answer. None of the mathematics (or physics for that matter) that I do can really be applied any where, which is the way I would want it.
My computer background actually started with Macs, but I didn't think much of it because the type of mathematics I do you really can't do with computers. I knew some people who did work on NeXT, Sun and Silicon Graphics systems, but I didn't actually start doing anything with them personally until about 1994. That year I did some work at the NSF Geometry Center which had 40+ NeXTstations, 10 SGIs and 5 Suns, which forced me to get to know those systems (though not to a very good degree because my research was still mainly done with pencil, paper and whiteboards). So a few years ago when I decided to take a break from school, I found that I had formed an addiction to studying, and computers seemed like a fun thing to study (specially systems where information on them was harder to find).
As for seeing other systems, it has been quite a long time since the last time I came across a non-Mac/non-Windows system in the field. The information I had gathered on NEXTSTEP/OPENSTEP did helped out with Rhapsody/Mac OS X Server 1.x and Mac OS X, but the main reason I liked those types of systems was because almost no one was using them other than me (which is why I still use Rhapsody so much today). Every time something becomes too popular, I feel the need to move on to the next thing (which is very much like the math that I do, which there are only about a dozen people in the world working in the same area I specialize in).
Admiral:
A PhD, and hopefully a professor someday.
Here is a sketch I did for my wife to show her what an immersion of the real project plane into euclidian three-space would look like (I was trying to tell her about my paper on tight immersion of the real projective plane with one handle).
