No, Its a bad review.
The author fails to grasp much of how Vista runs under the hood and seems to talk more about what is visually apparent.
At this point in time, however, Vista is not ready for Prime Time for a number of reasons ranging from hardware support lacking, multitudes of software not working and needing to be upgraded, as well as some fundamental design issues that will need to be addressed.
Most of these things should be worked out in the next year one way or another. I would be shooting for Vista around the time that SP1 ships.
The only people that should upgrade to Vista today are those who have very specific needs and those are few.
If I were to purchase a PC today that came pre-installed with Vista, I doubt I would wipe it for XP unless I found my software did not work. What I would not do is take a perfectly good XP PC and toss Vista on it.
Also if I was building a PC from scratch, I would not place Vista on it unless it was a secondary PC that I would not worry if it had issues.
