What features does vista have that XP doesn't that are worthwhile? What is pushing people to upgrade? Nothing as far as I can see.
Now you can buy PCs without an OS, and some very cool portables like the asus eeepc using linux, I'd expect MS dominance to take a major bashing over the next years on PCs. Not to mention the march of Apple.
You can't really start an article with "As Apple fanboyism has spread throughout the tech publications" and expect to be taken seriously. Especially when you then churn out obvious Microsoft fanboyism.
I think to be honest the whole point is becoming moot. The operating system is becoming irrelevent. Everything is moving onto the web (Despite ms trying hard to stop it by adding bugs and incompatibilites into IE ;) ). Luckily though IE is nose diving in usage.
Add to that the new motherboards that ship with linux for a fast startup into a browser, and what is the reason for most people to boot into a full blown monolithic beast such as vista?
