So, what I'm taking from this is that the author feels Microsoft should pull an IBM and basically completely withdraw from the consumer market. While it's true that Microsoft's best domain is in the enterprise market, I have to imagine there's more to it than them "wasting money" on IE, Bing, etc. AD is great, but even in the server space Microsoft has a lot more to offer than just one product.

I like the author's main point and I agree with it without hesitation, but I can't support the supporting arguments. Especially considering Microsoft is still a huge success in the desktop market (a market that isn't quite as dead as some seem to call it).
