An interesting comparison is the Corvette and General Motors. In 2011, GM sold 2,503,820 cars and trucks. Corvettes accounted for 13,164 of those, or .5%. And considering the Corvette itself, I'd bet the margin is much smaller than most of their vehicles. Wouldn't be surprised if they lose money on it. Still, it's a very important part of the Chevrolet brand, and they'd be insane to discontinue it.
I agree, that's an interesting comparison.
GM keeps the corvette because of image: It's great to brag that you make a car that can keep up with / outrun other "super" cars that cost 4 or 5 times as much.
Even if they lose money on each car they sell, they can still brag about how powerful the car is (and therefore how powerful the company is) and get free advertising.
Apple isn't likely to sell the Mac Pro at a loss and hope to make their money back on sales in the App store.
I don't see a lot of computers that perform the same as a Mac Pro but are much more expensive.
The Mac Pro isn't the corvette, it's the other super cars.
If demand for Apple desktops dropped to ZERO tomorrow morning, Apple would lose 3.7% of their revenue (who knows how much profit). That would sting, but the company would continue on mostly unaffected.
If demand for iStuff dropped to ZERO tomorrow morning, Apple would be in a world of hurt. Their would be panic in Cupertino and we would see some very desperate acts while they tried to figure out what to do next.
I love my Mac Pro. It is the best computer I've owned or used in my life. Not a doubt in my mind. And I don't think Apple has turned its back on or abandoned professionals.
I just think we're in line with all of the iStuff users. It's a long line and we're at the very end of it. We'll still get there, but it will take a while.
