Sorry, but Apple is not a 2-man garage play anymore...it's a behemoth sitting on 20 billion dollars. And Woz was never the single product man there, although he really helped in the Apple II line...there was a lot more people doing genius work for Apple, such as Hertzfeld and Atkinson.
Apple is indeed light and responsive to customers' demands...otherwise it would NOT reform Stacks in 10.5.2; it would NOT offer NVIDIA now; it would NOT launch a superthin notebook called MacBook Air.
I actually don't know ANY other company that comes close to Apple in terms of answering customers. They REALLY get your feedback. As for the fabled midtower, maybe it's just not requested ENOUGH, sorry...
And no, Woz does NOT work in a corporation that needs to evolve all the time...he would be great for thinking of whizbang gadgets in his big room and spending R&D money for little more than nothing...I'd rather have him in a sort of social responsibility or charity role; he would be awesome at that. Wheels of Zeus anyone?
