I'm only a budding ID here, and know nothing of the real world but,
from what I've noticed, there are many levels employed in the ID process:

You'll notice on Coroflot and other job sites; that along side the more heavyweights like SolidWorks, you'll see "Rhino" mentioned a lot as a desired software skill. Why?

What you'll really see at the core is that good skills in old-fashioned sketching (whether by pencil or electronic means) is still heavily desired - along with "ideation" skills.

The ability to conceptualize the form of a product with clear, unencumbered dexterity in an expedient manner...

I'm assuming that MoI would be a very good choice for the initial creative process of design. - it's NURBS library is Rhino-compatible anyways!

If a program can help you more fluidly bring ideas to life without the cumbersome machinations of a laden UI to slow your creative process, then any good studio worth its salt may consider MoI.

But like I said, there are many levels to the creation process - let the structural/machining engineers on floor-2 use the SolidWorks and CNC software to figure out the drafts, ribs, stress-points, nooks and crannies of the product casing thought up by the Rhino/MoI/C4D "ideation" artists on floor-3.
