I use mine mostly to learn coding.
I am slowly but surely learning C, with some interest in OpenGL, and I always make sure that my code builds on all machines that I own.

Simple OpenGL is super to be able to visualize the ideas expressed in your code and go beyond stdout.

I'd say I use my Octane some 4 hours per week, and I will probably look for another system that I can use for more experimentation, since my Octane is fully loaded.
I also use a HP-UX machine some 4 hours per week as well.
