Do you have a source for that 30-35% figure? To my best recollection, the Mac peaked with ~15% market share in the early 90s.
Quote for freakin' truth. The Mac has
never had a market share above 15%. It was only the Apple ][ that dominated the market. But that did not translate into automatic market domination for the Mac.
Of course, the strategy of market share above all else also almost bankrupted the company.
Also, what almost bankrupted Apple was not a market share above all else strategy, but rather an increasing tendency to neglect their consumer line-up. The Performas were s__t computers. I owned one, which happened to be one of the worst Macs ever made: the Performa 6200CD. It almost made me a Windows user. At the time, the high-end Macs were fantastic, but the Performas were horrible.
During Steve Jobs' absence, Apple didn't put market share above all else: they put profits above all else and let the quality of their computers suffer. Apple created tons of different choices for consumers which just ended up confusing the hell out of everyone, and they had so many different side projects that never went anywhere and were just soaking up resources (Newton, Star Wars, Pippin, etc.).
Apple was losing money, yes, but they had tons of cash and Apple was never in danger of going bankrupt. Their hard-core Mac base stuck by them (including me) for most of the 90s as well. What almost put Apple out of business was that their products were just crappy, and the operating system was languishing while Windows gradually incorporated any advantages that the Mac OS had at that time.
When Steve Jobs came back, he focused the company's efforts on the Mac, simplified the product line to a simple product matrix, axed all side projects that weren't actually producing any results, and slowly built a comprehensive strategy for the future of the Mac OS. Today's Apple shows all the results.
That's why I've been seen on these message forums lately decrying the decline in quality in the iMacs and the slowing down of Apple's update cycle for the Mini and the iMac. Right now, Apple's doing great, but I see them veering back toward that old attitude of neglecting the consumer machines while spending too much time with the high-end boxes. That's exactly what happened in the mid-90s.
The Mac mini and the iMac are still good computers, and offer pretty good bang for their buck. Just because Apple doesn't update them often doesn't mean they're not good. (In fact, it was the Mac Pro that was the most neglected computer until the most recent update -- it went for about a year and a half without any really significant updates.)
