Bullshit. Apple competes in the tablet market with MS, and a whole range of other manufacturers. They compete in the phone market with Samsung, Nokia, and others. They compete in the laptop market with many other manufacturers. By your account if GM decided to start making bicycles along with cars, they suddenly wouldn't be "competing" with any other auto maker that doesn't also make bicycles. That's a crock.
Do I need to re-post it so you can read it again??
