I think it's far from obvious when you've been unable to point to one concrete (even biased and opinionated!) example of why you think a Macintosh computer is inferior to the technology you choose to use.
I'm not trying to convince you of anything. The burden of proof lies with you.
Read the facts. Windows has what, like 86% of the desktop market?
I think you might be confusing facts with statistics? In any market you choose to look at, you can find a high-quality alternative to the commodity product offering that has a minority of the market share. BMW is the oft-quoted example in the automobile industry. It would be a mistake to claim "A BMW clearly doesn't outperform a Ford Taurus because there are so many more Fords on the road." Their relative market share clearly has no bearing on their respective performance.
