It's not just Windows where this is the accepted practice. On multiple occasions I've brought in ailing MacBooks (and MacBook Pros) to the Apple store and the only advice the "geniuses" have had for fixing the problem has been a clean reinstall.
It's frustrating, yes. But I don't think the problem is the product, nor the industry. The real problem is that operating systems are complex beasts. The consumer has spoken quite clearly that the most important thing is new features and functionality, not stability. Someday hopefully we'll have our cake and eat it too, but for the time being I don't think we'll be getting away from these issues.
