I agree with the others but; design should be important in enterprise applications as well. I have seen many enterprise applications which were designed so badly people can't really use them very well. Of course I am not talking about fancy design things, but their usability sometimes... argh. Though they need to cut down money on something, so they focus on the functions instead.

But - if you want to get attraction (like said below) you need to focus on design. You won't look at a Mercedes if it was ugly.
