Here's a quote from one of his other articles, "I can't say that I've looked at Windows 7 nearly as closely as Kennedy has, but I've looked at Windows 7 enough to know that it's no real improvement on Vista."
It's too bad that "journalists" can be consistently wrong with impunity.
That said, based on his track record, Windows will probably have a bright future.
I think that Win8 could be saved if MS just published a few registry tweaks, combined with a checkbox saying that "No, I don't want to use Metro, ever."
But it would require someone in upper management to admit they were wrong. They would get a bad review. Sadly, it's better to let customers go and let revenue slide than to admit that you were wrong, in a company like Microsoft.
But that said, Windows 8's improvements are pretty much all under the hood: they're not user-facing. It's no wonder people don't see them, because the improvements are not designed to be seen. Unfortunately, that also means they can't really be marketed except in very niche scenarios.
