well, it takes all kinds of skill sets to undertake a large project.  I seriously doubt that any one person "designed" an IPod...

No doubt you need designers and artists to come up with the design, but the design has to be fabbable (hence you need engineers) and has to be acceptabel to the market (hence you need people who do market surveys) and you need people who can build, and test, and a sales staff....

And then, once your project becomes sufficiently complex, you need "system engineering" to put it all together (this is what Steve Jobs provides).  The IPod (and the space shuttle, and the moon program) was all put together with system engineering.

But, if you promise not to go around denigrating engineers, I promise not to go around denigrating industrial designers.

Well, I promise not to go around denigrating industrial designers regardless =)
