It's the finished product that counts.
Not in security relevant areas.

I have seen some very poor professional products where I wonder why the engineers are not in jail, and I have seen amateur products built as a hobby that are 'par excellance' that would put many professional engineers to shame.
Examples ? I have never seen an amateur designing an ipod like device. Especially concerning the thickness.

The less known, the more professionnal.
The less known, the less trustworthy.

Heard of Cypress ??? what do you think of their PSoC Express ???
Heard of Freescale ??? What do you think of their Processor Expert ???.
I can't see a connection to the topic.

The ability to match processing power to the application is an
important consideration when designers select a microcontroller.
Yes. There are compareable products, which have the same processing power but are not used by hobbyists. I think it is a curse for b2b if your products are mainly used by hobbyists. Well, hobbyist does not need to be equal to producing amateurish products, but this is how it is perceived often.

For a mass production, the goal is to have adequate processing
power at the lowest possible price.
Yes.

What kind of applications do you have in mind?
What do you mean ?


The perception of something amateurish or professional is in the eye of the beholder.
I am talking about professional people in the working areas being mentioned (mainly security). Imagine a power plant where the brown out bit is set in a pic and the pic suddenly stops working.

Just because you get paid for doing something doesn't mean you're any better than someone who doesn't.
You invest more time in the same thing. The same as in university: You know a lot more than someone who has not studied a subject yet. There is a higher probability that your circuits are better because you know more approaches to a solution.

Definition of a professional company? One who has better PR and a stronger salesforce.
Yes.
