Interesting theory, but read this quote from the first page of comments:

"Thanks.. I am having the same issue. When I started using the laptop at the end of last week I thought I smelt something odd. Well.. here I am Sunday doing some work on the couch and my wife says "what stinks like cat pee". I said.. I think its this laptop.. puts her nose up to the keyboard and BAM! It really stinks."

Some guy AND his wife noticed the smell. If you're right, that's one hell of a coincidence.

Not if they are both of the same genetic pool. For example if they are both Dutch or Korean etc. Especially if the 'not smelling' it gene is the less common one (and on ethnic boundaries). For example all of the workers were Chinese and Chinese don't have the gene.
