Entrepreneurial physics?

NetMage

Is a MSc in physics a high enough degree to pursue a start up company in computer technology (embedded systems). Or would EE be a better suited route for something like that. I am not against getting a MSc in EE but I enjoy the fundamentals and purity of the science as opposed to engineering. Also I was thinking maybe a MSc in comp sci would be a good double. In the unsuprsing event that the business doesn't take off I feel the double masters in physics and comp sci would lead to a safe job developing software or hardware.
