I knew this would be the first post. And I am so disheartened to be proven right.
Just because Apple has billions in cash from successful products, does not have any correlation whatsoever to their ability to enter a new market (both new to them and to industry as a whole) without making mistakes. I'd like to point out that in no way do I think Apple should avoid the sector, as the GM former CEO states, because as a company devoted to quality, and who has tons of resources ($$$), they'll be hopefully able to do it justice. But just because they have the means to toy around with the idea of a car, do extensive research, etc... doesn't mean they know exactly what they're doing. Generating billions of dollars in profit on consumer electronics doesn't indicate they know how to make a car.
I think the point is that it's silly to underestimate Apple and assume they will fail, given their impeccable track record.
