In fairness, this is part 5 of a review and I haven't read the first 4 parts yet. I will as soon as I find them, and I urge you to do the same.
As you read this mind-numbingly scathing piece, please remember that the author is a genuine Windows fan and supporter. I truly believe that he is writing this piece in the hopes that Microsoft will listen and fix some of the most aggregious things before release. So as harsh as it is, read it as constructive criticism from somone who dearly wants to see Windows Vista be a rousing success.
