Ask HN: What course should I study to develop "Startup Skills"?

tl, dr; Do I need to study 'computer science' subjects to build a startup or are practical subjects just as good?

I've just finished my first year studying IT and am at a crossroads. I have the opportunity to relocate and pick up a Computer Science degree, I am hesitant to do so due to the fact that I have to relocate firstly and secondly not gain credit recognition for my studies.

My second option is to continue studying my degree http://www.handbook.uts.edu.au/courses/c10148.html#CCR . I enjoy studying my course but the subjects are not what you would classify as "Computer Science", my question is this - Am I missing out on much by not studying Computer Science subjects?

I don't plan to work as a Software Engineer for a company but rather start my own company. As such, working as a Software Engineer would not be for the duration of my working life.

The course I'm currently studying is very practical and relevant to todays technology. Subjects I'm enrolled in next year include Cloud computing and SaaS, Web Services Development, Interface Design, Application Development in iOS and Enterprise Development with Cloud Computing. Plus some core subjects of my major (Data Structures and Algorithms + System Development Project).

While these subjects are very practical, I'm wondering if there "too practical" and in further years that I would be left behind by new technologies based on only studying todays technology. It might be paranoia or could it be that I should look to study more general computing subjects?

I'm not sure if I've worded these questions correctly but hopefully you can grasp the idea that I'm getting at.
