David Vronay writes in his blog that "One of the first things people notice when they start using Vista is the absence of menu bars." accompanied by this screenshot: .

I won't deny that things have changed, but I wouldn't say there are no menu's left. Not unless you think that a menu bar can't have any icons. Microsoft calls this invention the "command module". I don't see why it's not a menu. Granted, it also has some characteristics of a task-bar, but when you bush a button there's still a menu coming out of it.
So the claim that Vista does away with menubars is only true if you stick to the strictest definition of menubar. Unfortunatly this claim seems to suggest that menu's have gone altogether, but that is just misleading.

Paul Mockapetris has written a paper in which he claims that IPV6 presents a danger to DNS. In my opinion most of this is nonsense.
He describes two problems. The first problem is that a DNS server might return an IPV6 address for a server that does not support IPV6. This is clearly a configuration error on part of the administrator, not a fundamental problem in DNS. IPV6 addresses do not magically appear in DNS, they are purposefully put their by DNS administrators. If such an administrator puts in wrong information, that his mistake. Not a problem with DNS. The same thing is true for IPV4. If the server answers an address where nobody is listening, it won't work. So unless administrators are intentionally going publish wrong information no problems should occur.
Compare this to car-navigation software that directs you to drive onto a non-existant road. This will not happen unless somebody put that non-existant road into the database. That's a human mistake, not a fundamental error.

The second problem is that your browser/OS will try to guess the proper name for non-existing names. So if you look for "hotmail", the system will try hotmail.com, www.hotmail.com, hotmail.net, www.hotmail.net, etc....
This has worked for IPV4 for twenty years. It's not a very good solution, but it's not a real problem either. Things will be exactly the same for IPV6, except that it will make more guesses before giving up.

The main problem described is the increased load on DNS servers. This is probably true for some big DNS servers, but not for the vast majority. Most DNS servers don't do much. Most of the time they are awaiting new requests, and they can instantaneously answer.
Even a tenfold increase in DNS queries will go unnoticed on most DNS servers.
It might be a problem for some big ISP's, however these guys are constantly upgrading their systems anyway. Each domain, (and therefore, each ISP) should have 2 DNS servers anyway, and even the biggest ISP's seldom have more then a handfull. Expanding that service is very straight forward, and completly built into the DNS protocol. Just add a new machine, change a few settings and your done. Nothing fancy, nothing that any admin worth his salt should have a problem with.
Even though it might not seem so at first sight, IPV6 simplifies networking a lot. ISP's can save money on routers to compensate for an increase DNS load. (Ok, I'll admit that's wishfully thinking at this moment).
A mitigating factor could be that more and more people are getting cable/adsl-modems with a built-in DNS cache. That can significantly reduce the load on the providers DNS servers.

All in all this feels like an attempt to draw attention to himself.

Microsoft published guidelines for computer-builders, on how they want Vista computers to look.
Somehow this feels like a desperate attempt at getting people to consider Vista. They are trying to appeal to the "dumb housewife" type of person. If you have ever seen a (stereotypical) married couple buy a TV you know what I'm talking about.
Typically this goes something like this:

husband: "Ok, let's buy this 100$ television. It's the cheapest model with all the features that we need."
wife: "eh, I don't know, I think it's kind of ugly. I think we should by that 800$ tv over there."
husband: "But that television doesn't do HDTV, and it's very expensive...."
wife: "but I like it and it has a built-in DVD player"
husband: "but we allready have a much better external DVD player"
wife: "it just looks better. I wouldn't want that ugly black box in our living room."

In the end the expensive television is bought.
The same thing happens with cars or any other situation where neither partner fully understands all the technical aspects of the decision.
That also holds for computers, especially now the megahertz myth is comming to an end. Even most professionals and hobbyists can't tell you what processor gives the best perfomance / bang-per-buck without consulting benchmarks. To the laymen it's impossible to compare computers on technical specifications.
Microsoft knows that, so they hope that people will compare computers by their looks, and therefore buy the wonderfull looking Vista computers, regardless of their real needs.
